It really isn't. 90 Muni for a squad wipe = OP, 50 Muni to kill 70 fuel unit totally fine? That's complete nonsense
What the hell are you talking about?
Invisible demos = quickly place a 100% accuracy B4 shot on the ground and delete whatever you want unless swept and destroyed from afar. This is also stock. The alternative is to go Counterattack doctrine and make a b4, which is easily counterable by direct and indirect fire, not invisible and not accurate, not to mention extremely costly in comparison. The alternative is easily countered without needing a sweeper, unless it’s a Goliath which has audio cues and is doctrinal.
Tellers = basically stronger TM28 mines, they one shot a LV but cannot be detonated by infantry. This is stock and available only to a faction that does not have a light TD for the LV phase stock (Puma) to compensate. The alternative is a TM28/Schu/M6 mine which are either stock or doctrinal (usf) and detonate by inf and deal slightly less damage to LVs, enough to cripple but not kill. Both need a sweeper to counter.
Again, if these two are the same to you then you are 1 billion percent clueless. This is not debateable.
