LOL. You have reinforced my point with reference to 3.5 rules, which is the set of rules this game was designed from. DPS needed the Magic world. Its a simple matter of fact. Magic doesnt stop at buffing.
As far as the balance issue, sorry, D&D was never supposed to be perfectly balanced. THAT is why there was always a need for PARTIES. Keeping a level of imbalance REQUIRES the need to work together to accomplish a common goal.
If EVERYTHING IS BALANCED, there'd be no NEED for teamwork. Limited need for specialties. Limited need for tactics. It would be a very 2-D world. And it would not be D&D.
In the current state of DDO, CC builds can NOT "participate meaningfully" in Amrath level and epic level content with blanket immunities and the nerfing of the CC playstyle (messing with heroic surge in current format, as well as under-clocking fascinate and other spell durations) successfully spreads this disadvantage into "non-end game content."
