Dealing with Summoning Mobs on Druid

[Bulzie]

Any tricks to soloing mobs that can summon on druid without a pet? I have tried in Seb to root, put back into corner and start casting say Winged Death and when summoned, just back up till in corner again and hope spell completes since i am back in same spot.
Any items or druid spells to help with soloing summoning mobs?

Bonus question, any way to use bear pet successfully against higher 50+ level mobs? Thinking have to be some kind of melee with a self ds (heals when can) and have bear on other side attacking? Just don't think it will do enough dmg to make it worth it.
