After reading this I have little faith in the explaination. Healing & CC was a big part on harder difficuilties.
It just seems to have been "consolised" and a huge amount of stratagy removed from it. Will there be spell combos?(Had a quick search and didnt find anything) Looks a bit like nerfing the game for profit so anyone can jump in and run around pushing buttons.
DA:O had mana and stamina regeration, you run out of mana and you cant heal. No infitite potions to replenish it either. If you let your healer die in a big fight you were often screwed so you had to make sure you kept an eye on each fight and kept them alive. From the gameplay videos it just looks like lets all DPS with our new flashy moves.
I was hoping for another good game from the lines of Baldurs Gate / Torment / DA:O.
Hopefully I am proven wrong, as I was really looking forward to this game. But I'll just wait for the reviews.
First of all, there's more CC in this game than in any DA game previously.
Secondly, there may have been a finite number of potions, technically, but in DA:O there was no cooldown for using them. Keep buying them and you'll have a nice stock. If you're using all your potions in DA:O, you're doing something wrong.
There were party combinations that didn't require a healer, and it was still possible to do well. In DA2, I had Sebastian, Isabela, and Fenris. There was so much DPS enemies died left and right before my mage could react.
If you want to know specific abilities then look up the Skill Tree thread. They've posted almost entire trees for mages, rogues, and several trees for warriors.
The new combat is stepping away from healing- for the reason of minimizing game frustration and adding balance.
Instead of the enemy having chain CC (I was playing DA2 and my mage was chain stunned for days), which causes incredible frustration, they're wanting to focus less on that by removing healing. The reason heavy CC, and powerful one-shot abilities were in the game were to balance out the incredible healing that could be done. The devs would have to take into account the extra HP you'd have by healing. One-shotting (or massive damage) abilities made you react by healing.
This new method isn't about reacting, but rather preparing and preventing. You'll have more control over your character (enemies will chain CC far less often), therefore it'll be less frustrating to fight certain enemies.
THAT is the main reason they changed the system. Not to "consolize" anything.
