It looks like you can't really handle the freedom the game offers. You should try looking for more linear games. And your opinion about exploiting... I just hope you're trolling. But I have been on the internet long enough to realize you may very well not be.
i will play definitly with minions but still canot decide regarding main veapon,probably will be axe
You might want to consider the staff. Staff #2 is with 6 seconds (4.8 when traited) fairly spammable. It provides a nice regen buff for your minions, which will keep them around longer. And the three stacks of bleed are rather nice as well.
And would it be reasonable to assume that the poison cloud from death nova would act as a poison combo field? If so it doesn't make the choice any easier.
I love the MM spec because on the landscape it's so easy it feels like cheating. Mobs just follow the minions and ignore you completely. I don't care for the burst damage because there is no endgame to rush to, I will just play however I like and have a blast. My main worries are with the build for dungeons because I want to be useful there. It would just be rude to enter a dungeon and suck.
