I prefer the new system.
Hailstrike is broken right now and should only hit for half or less.
6 AP + Warlord + Pawn is plenty.
1 AP for free movement + getting more AP for every kill allows my rogue to kill 1-2 enemies each round which is more than enough.
Most Spells cost just 1 AP -> you can cast way more than you could in OS1 -> more fun.
