Yes - these two are my only purple heroes. I have 6 trap tools at my disposal right now.
I see riposte as a useful but limited defence mechanism for a tank - if dispelled it does nothing. Boomer ability has dealt some limited AOE damage at least.
Or should I just wait for better purple to pop up and put double red in defence?
I have seen defence teams sporting 4/70 Boomer as tank.- my other strong heros so far are Boril, Scarlett, Kestrel, Drake Fong, Chao, Gregorian, Peters and Gormek and i while upgrading I have favoured solid attack teams more than perfect defence.
