I just wanted to make a thread about this topic because the complainers are already making assumptions about the game and how skills will work without knowing how builds will end up mid-late game. They assume that the entire game from level 1 to max level will be spamming primary attack to build "mana" for your main skills, and using your skills sparcely yet in most of these types of games that is never the case.

To preface, the devs last aRPG (Chaosbane) has a similar system where your main attack, builds up your "mana" to use your more powerful skills. However if anyone actually played that game more then a few hours they would know that by mid to late game your passives, gear, stats and other things allowed you to consistently use skills without even using the main weapon attack so the "generator" part was nullified based on your build.

While we don't know how endgame characters will play/feel in this game, I'm pretty confident that the core gameplay loop will evolve to more skill usage and less primary attack usage (unless you want to build your character that way).

So lets all wait until EA where we can level some characters from scratch before assuming the entire gameplay loop never evolves from the generator/spender type of gameplay.
