So i've been wondering, i see many people going with trans for trait. But if you maths it out doesn't the mana trait offer more healing with the added versatility of using it for damage or jumps.
At lvl 20 the mana talent gives back 16 mana and the healing talent heals for a tiny 160.
It would take four procs to get enough mana for a BoH. At level 20 it heals for 548 to every hero around, potentially your whole team. But we'll just say it only healed you. So that's basically 137 health to one person per proc of Insight, just slightly less than the 160 you would have gotten from Trans.
But the big difference is that BoH heals everyone around you. Four procs of Trans would be a whopping 640 to ONE person. But over the same course you would have healed, at the very least, two people for 548 (1096 in total) with BoH. It just seems to me and maths that Insight is the only option for healing.
I think the assumption with Insight is that it only gives 12 mana back all the time. But maybe i'm wrong. I guess i just love never needing to fountain.
