Skirmisher nerf when

When airpads have 10 build power per pad.

I wish we had graphs that showed what the most used units are (in terms of metal expenditure per battle, including incomplete units).
It would also be nice to then analyse whether there's units that are more often present on the winning side (may get badly confounded of course, e.g. those who made more mexes are probably going to win).

My guess is recluse and rogue. Maybe buoy but that abomination doesn't show up often in land maps because of how slow it is.

Recluse is a particularly bad offender, being all terrain and with AoE.
Recluse spam+a venom or redback is very hard to counter.

Skirmishers feel fairly balanced to me.

The really strong ones like recluse cost a fair bit and that gives you a while to react before they become OP. Rogue I feel isn't "really" a skirmisher but more of an artillery unit in shields. Because I find shields are best used in bursts (attack, retreat, recharge, attack again) I load up on Rogues to have a punch vs static defences.

But anything in huge numbers can feel overwhelming, I guess.

skirmishers are the best when you like some grinnin.
