How can a bard solo a summoning mob?

[Puluin]

When mez works, I had some luck with timing mez + dots. time mez to land just after server tick. this seemed to work more effectively than tank n spank on certain mobs in Skyshrine. When i hit 50% hp i would let dots die and just mez + regen hp. mind you this is entirely situational and is only effective if you have excellent timing.
