"You stack initiative? that's an exploit"

-> That is build decision.


"You kill a merchant? That's an exploit"

-> That is hardly something you would do in real, and if soon there would be hardly anyone left to trade with you. The exploit here is, that there are hardly any drawbacks.


"You shoot before waiting for the combat to start? exploit!"

-> This is just tactics, and will be 'punished' with delay on the second turn, if attacking from sneaking after the first attack. Exploit would be keeping the leader trapped in talk, while killing is team.


"You... BUFFED BEFORE BATTLING?! Exploit!"

-> Buffing before first strike is tactic aswell, but I don't like the fact that you can get your whole team 'rested' buffed just by one click using a bedroll, but for me its less an exploit and more a design flaw. Using other buffs normally means, they last less longer, because time runs faster outside of battle.
