My character is level 41 and I can't post in the forums? That makes absolutely no sense.

First of all, how high do I want to level up Thaumaturge? A few people told me level 26 so I can get swifcast? Is there any need to level beyond 26?

Do I want to level any other classes for their cross class skills?

Do I want to level up to 50 playing Arcanist or Summoner? Summoner is working great so far, so I'm guessing it probably doesn't matter.

What is the reason for Ruin 2? It has exactly the same damage as Ruin and with the GCD it takes the same amount of time. Is there any reason to use Ruin 2 at all?

When in my rotation do I want to use Fester? Should I just use it anytime I have all my DoT's up and it's off cooldown?

Lastly, before I knew kinda what I was doing, I assigned a lot of points to INT but I used points elsewhere. Do I want to go and reset that and just dump everything in INT? If so, where do I go to reset the points?
