I would like to say I'd be completely fine with altogether removing the sniper's AT abilities and just making him a standard sniper that actually gets decent veterancy bonuses (higher ROF, etc) and then giving either the IS or Sappers an AT snare. I'd rather have a sniper than can be more anti-Infantry oriented (the thing they're kinda designed to be) and have a better window to countersnipe (doesn't have to aim for a year and a half and have the Ost sniper recloak if you don't target him right away).
It would also help Brits to deal with their now brought-in-line AT gun cost and give them away to prevent heavier vehicles that the sniper can't even crit decently from rushing straight past a couple of AT guns and anhiliating them while the infantry just watches.
I've been playing a lot of this mod as it develops and I still firmly believe Brits will need some sort of snare now that there's literally nothing stopping a scout car (or even better, double scout cars which were pretty damn effective when the sniper still had it's vet 0 critical shot) from rolling right ahead on a UKF sniper, and if an Ost player is good enough to keep his own sniper on the ball while he does this, that sniper practically never existed.
So please, remove the critical shot if you must (even change the sniper himself to a regular, anti-infantry, non-AT sniper for all I care, as said above) but give the mainline infantry some kind of snare so the UKF sniper doesn't have hide in a corner and be useless until either a scout car makes a major fuck up and manages to stand in front of 2 AT guns, or for the Brit to invest in a completely overpriced and useless light vehicle vehicle that also locks out one of the more useful emplacements (not that emplacements are good anyway but still
)
