Not bad Scream, I would normally agree with those stats due to the fact that Mortars in reality would be far stronger than the stats I have given mine but I feel the game just wont support it with the pre-existing stats for other units.
The Ignore cover idea... I personally would buy some Gorgons for that job even if they are dearer per battery and given the choice I would probably prefer to pay for Basilisks than support artillery at 100 points. To me that just makes stats/points value. The conclusion for me is that Support Weapons must be cheaper for anyone to be tempted to take them.
I was trying for a smaller support section that was cheap enough that you could throw one in with most infantry companies or as your last choice to fill the +25 point gap that is sometimes left.
I've used these for a year now and play wise the extra barrage template is no better than a few tactical stands with the exception of the extra indirect attack. But if the enemy bunches up then that's where the Mortar (In real life too, I would imagine) excels.
However, as well as the Light Mortar Section I have also been trying a heavy mortar. If the light mortar section could be equated to a WWII Platoon Support 60mm or 81mm Mortar that allows fairly decent fire and relocate options...

IG Heavy Mortar (75? points, BP 2, 3x units in a battery)
Immobile, - save, -3Caf, Heavy Mortar
100cm 6cm Temp, 2BP, -1TSM. (Immobile, Artillery, 6cm Temp, Tow)
Most of these were originally added to the PDF who needed as much extra firepower as they could get because of the lack of heavy ordinance IMO. I then allowed my IG to use the Light Mortar as it just made no since not to.
