I have some questions for all you technical testers or benevolent devs out there. 

1.  Do the same abilities stack?  If I use Ub's Spit and then renew my cooldown to use it again before the first DoT expires does the damage stack?  What about if two players are UB and use Spit at the same time.  Do both DoTs proc?  (you see slow effects replace when the same, not stack, does this also apply?)

2.  Do the same auras stack?  Will two UBs using Ooze at the same time slow the attack speed of an enemy within range by twice as much?  Will two Sednas with regeneration aura increase allied health twice as fast?

3.  What about stackable combos like Ice TB?  If a target is frost nova'd and rained on by two seperate TBs will a shatter from one of them get 4-5 x damage?

Thanks, Kestrel
