I fully agree with iFLAME's words :
In Divinity II is so nice to make a strategy plan

And the funny thing is if you don't make one sometimes the fight is fast over because of Game Over or it was an easy fight that didn't need a stratey plan (so you're the lucky one).
But I like it to think about my next move/plan. In most situations there's always a strategy plan for each kind of character/gamer's preferred or favorite skills, I'm sure !
Stat points aren't that important yes, althought it can make a fight more enjoyable if your manapool is big enough when playing a character that uses many mana in battle (like a Priest/Mage).
Of course you can always use a potion now and then, but it's a little bit too frustrating if you need to SPAM many potions, that kind of "strategy" I don't like ...
for me strategy plan goes about using a skill or combination of skills & tactical moves ! Good luck everyone, enjoy your battle
