I don't need to write an essay to explain my thinking. Poison mage gameplay was bad. The summons which are the core thing about summoner were also bad. There is no need for me to articulate this further. There's nothing vague about it. The class was a broken disjointed mess that was trying to be everything at once, and now they've fixed it by giving it a focus around summon magic. I am thankful that Yoship gave us a summoner that feels like a summoner now.

You can choose to continue debating this issue if you wish, but you will not convince me that 5.0's warlock is better than what I've seen of the summoner we are getting in 6.0.
