110 vs 120 mystic/focus for t-hunting

[phazcow]

I haven't even seen a 120 mysticism scroll on my shard (Chesapeake) and the focus ones are pretty expensive. So, right now I'm running with 110 mystic/focus and it works great for level 5 maps, 6 maps are another story though. It can take as many as 20 or so colossi to take down a greater dragon. Would the jump from 110 to 120 make these a lot easier?

It would make it easier but I would not say a LOT the colossus would be tougher and harder to dispel
