My biggest grievance since their modernized Xcom is the fucking start with a 4-man squad limit.
Enemy pods will usually have 3 enemies, making any early engagement a 3 vs 4 affair, which can quickly spiral to a 3 vs 6 if you run into another pod. Doesn't help your beginner squad has no useful ability of note outside a grenade.
Late in the game, pods STILL have 3 enemies (though stronger ones) but you have a 6 man squad armed with freeze bombs, wrist rockets and psi powers.
I may bit the bullet and just install a mod to make the game start with a full squad, balance be damned.
