I can’t say that better than @VOLAND.
Alpha striking for BOTH SIDES is the mother of all problems that simply make the level of difficulty unfair.
VOLAND:
Conclusion: alpha striking is making the game seem much easier than it actually is when the devs look at their stats.
As an an example:
If players who have mastered alpha striking (terminator builds) knock out 15 enemys in two turns, pure statistics would say that there are probably still too few enemys.
Another (inexperienced) player who hasn’t discovered these “OP” builds then wonders how the hell should I deal with this number of opponents. And that’s the unfair thing about it!
