Which hero is the best in the Tribes of the East expansion?

best Vaishan and Iranna: Vaishan gathers hunters, and their invisible archers are as good as dragons. At level 20+, they clear the map and immediately grant luck. Take a lucky sorcerer, and chaos thrives with Arcane Wave, dealing up to 3.5k damage (with absolute magic, you can hit at least 10 dragons, except for lava dragons, which will be around 8...). And Iranna destroys with furies (or megarons, depending on who plays whom) (if there is Aura of Swiftness and Windstrider Boots, they run around the entire field from the back row (where they can only be reached with emeralds and black artifacts, and if there are 2 artifacts from the necromancer set, no one can reach them at all) and the enemy army must die :) ) all on the field... only bad in sieges :( but what can you do, there is no perfect hero :)
