I don't know a single Warframe player that isn't annoyed by this, including veterans.

Well, now you know one.

It's hard to explain, but sometimes I feel like modern video games spoonfeed you too much information and make enemy tactics too obvious. (I'm a WoW player, so I may be a bit biased.)

It doesn't bother me if an enemy doesn't necessarily give a visual cue for me to avoid. It makes them more threatening, and it forces me to react to an attack to survive. (Besides, is bullet jumping through levels and ignoring 99% of the enemies really that fun?) At the very least, you know what enemy to look for after getting knocked down, dragged, nullified, etc. I mean, god forbid you have to stop and shoot something.
