I've been playing constantly for the last two weeks and thought I'd give my balance impressions. Overall balance seems pretty awesome atm, or at least the trolls havn't figured out what to abuse yet.
FirewalkerI thought it would be OP, but actually not sure it is. The only problem I have with it at present is that it brutally counters the whole shieldfac unless the shields huddle under an apsis.
Pyrostill needs standardised projectile that only damages each target once per projectile
Scorcher & RavagerScorch & Ravager feel pretty weak nowadays. I think this a product of not just the scorcher HP nerf (which made them much worse vs light defences), but the buffs to missile targeting and numerous skirmisher type units in general - scalpels, ducks, slashers, wolverines, moderators, firewalkers, banishers - these kind of units punish vehicles with their slow turn circles. LV meta now seems entirely focused on creeping with wolverine and slasher, which I find a bit sad given this factory used to be about balls-out Ravager led aggression.
RecluseHaving used spiders a lot recently, I don't think the Recluse cost 300 -> 280 has improved them enough. I'd still rather build rocko, rogue, scalpel, slasher, wolverine or moderator than Recluse.
PantherThese seem pretty bad.
TremorThese also still seem basically useless. The firewalker does the same job (area bombardment/denial, making shieldballs and light defences cry) but more reliably, with more mobility, and for half the price.
Peace.
