Outside of the obvious monk what spec do you expect to net the highest win percentage in RA?
As I usually have no healer and alot of healers I finally get into my team aren't useful I started playing healer myself ~ a year ago. But because
I'm too bad to play monk dervishes have more style it had to be a dervish healer.
At least for me playing this results/resulted in frequent good runs and 25 runs. Enjoy playing it.
P.S.: If you play dervish heal your dervish has to be bald.
So Grenth Dervish is the clear front runner among offensive specs for carrying games?
Also, I'm curious as to what feel are the top 5 or top 10 most played/effective specs for RA. I'm coming back to the game soon and am trying to kind of figure stuff out.
The most effective build is of a shape such that it counters most relevant threats/time wastes you may face and is thus highly dependant on the current Meta which is a permanently changing. Therefore no one can give you a most effective build; there is none.
As your question is of pretty general nature so shall be the answer. Run a build that's flexible, may be ran either offensively or defensively depending on what's currently needed, isn't focused on a special scope of enemies, isn't too easy to counter by rupts, facile enchantment removals or physicals as these are somewhat frequent. Some examples of how such bars might look:
And if you loosen some of the earlier mentioned features you want from that build of yours you could even take such bars as these:
P.S.: No build guarantees carrying no matter what your opponents run. If you aren't a good player you won't carry at any point. If you are, the concrete build choice is of little impact.
