I was thinking of starting a new thread to take stock of the current list's status, but this one seems appropriate.
First a question to Chroma : I've seen you mentioning a "next version" in several recent threads now. You've got me interested there, any idea as to the release date?

I think it's getting more and more important to have that next version as there are now 4 or 5 variant lists, each going in different directions... It's getting confusing.
From what I've gathered, here's a summary of the "hot" topics:
SPECIAL RULESGeneral concern about the length, complexity and/or number of special rules.Most of them are OK, I think.
Tyranid Swarms and
Tie-Breaker could do with some kind of simplification, though.
- Tyranid Swarms > Get rid of the rule altogether and replaced with fixed formations? Initiative-based system to represent synaptic control? Remove Synapse coherency? Remove Brood reorganisation? I would remove the synapse coherency part. It really doesn't have much effect on the game other than slowing things down. As Chroma said, you'll want to keep your synapses in the middle of the swarm anyway... and if you don't and try to extend the swarm to control several objectives, you'll weaken the synapses.
Brood reorganisation could go too : it's nice, I've used it from time to time, but it doesn't add much. Spawning is already a form of brood reorganisation.
The initiative-based system is nice but I prefer the current one: broods go *pop* if you kill the synapses and can come back later via Spawning. Plus, it works fine.
As to fixed formations, well, I also like the current system better. It gives the Tyranid player more options and does not overly complexify/lengthen the game.
Relentless > Only +1 bonus to rally rolls?I like the rule as it is. No need to change it in my opinion.
ExpendableI've seen no complaints on this one... and I don't have any either.
MobilityDitto.
Spawning > Remove the rule in favor of cheaper units? Change it?I wouldn't remove or change this rule : it's taken a long time to balance it and it now feels OK. Plus, it's thematic and it works just fine. It does lengthen the game a bit, but not that much.
TunnellerNobody seems to complain about it, but is it really necessary? One possibility would be to simply give the Trygon and Raveners
Teleport and boost the cost of the Subterranean Swarm formation accordingly.
ObjectivesNo problem here.
Break their SpiritNo problem here.
TiebreakerAgain, one or more examples would be fine. More than fine actually, necessary. Maybe it's me, but it never fails to confuse me whenever I have to calculate the VP with Tyranids.
UNITSMost units are balanced (always a good sign), with one exception: the Meiotic Spore Pack. As far as I can tell, it's almost never used. Considering how badly Tyranids need AA cover, this is telling. Suggestions vary on how to make it better:
- Reduce the cost of the formation to 125 points.
- Give them
Scout.
- Extend their weapons range to 30 cm.
I will, of course, add my latest suggestion.

Quote:
Meiotic Spore
Type - LV
Speed - 10 cm
Armour - 5+
CC - --
FF - 6+
Weapons/Range/Firepower
Spores/30 cm/Special, see notes
Notes
Skimmer, Scout, Cannot March, May contest but not hold objectives
Any aircraft moving within range of a Meiotic Spore automatically receives 1 Blast Marker
Yet another special rule, yes, but a incredibly simple one. It would allow the Spores to cover more ground (their biggest flaw at the moment) without making them too powerful (all they would do is laying down BM).
ARMY LISTFixed formationsThis is one possible solution, but I love the current system because it's so flexible. You can pretty include whatever you want in your swarms. It seems complicated at first, but you get used to it rather quickly.
2-1 ratio for Common/Uncommon ratioNot a huge problem, but it would be nice to have more diversity in army lists. I'll copy & paste my latest suggestions:
*** Make all Common Broods cost 100 points > 4 Gargoyles for 100, 6 Gaunts for 100, 3 Raveners for 100
*** Have a 1-1 ratio on common-uncommon broods
OR
*** Make all Common Broods cost 75 points > 3 Gargoyles for 75, 4 Gaunts for 75, 2 Raveners for 75
*** Keep the 2-1 ratio
Both solutions have the side effect of making Raveners a bit more expansive, but I guess that would be OK since you would also have an easier access to the bigger guys.
Raveners & Gargoyles as Brood AND Independant unitsAgain, not a huge problem but a potential source of confusion. Ex: do Raveners and Gargoyles from Independant Swarms go back into the pool for Spawning purposes? Is Brood reorganisation is kept, can they join other swarms in the end phase? More importantly, why can Raveners or Gargoyles act on their own in the Sub Swarm/Harrassment Swarm but, if part of a Brood Swarm, they disappear when they lose their Synapse?

I think this sums up most of the question. Have I forgotten anything?
