This has been a topic for a long time now. In one hand, some players would like to see a clean version of the game, something that can be called as “Glitch free version”. On the other side, others hold that the game should be left as it is.
As to what respects the “blast trick”, the opinions do not vary. However new reasons are given to why it should, or should not be fixed that the shaman may not lose health when hit by a blast, in case a spell is cast in the exact time she is falling. Down below you can see both positions, so you can evaluate your opinion among them.
What do you think of it? Is it a glitch or a trick? Have your say here in the comments.
