Quote from SeravokX
Reflect Damage is the only affix in the game that has no visible effect to notify the player of the potential of incoming damage. This is tough on a player who wants to use a tactic or skill designed to increase survivability to combat such a scenario. If a mob with the Reflect affix simply had a visible aura I'd bet many players would have a lot less trouble with the mobs.
And this is what is going to happen "soon". See the bluepost I linked.
Most of what has been said in this thread will be obsolete as soon as the RD changed go live - and it won't take too long, otherwise they wouldn't have mentioned it in the bluepost.
