Imo a sysmtem like WoWs spellpower system is something that will be required for this game before release
The important part is giving the magic users the same endgame scalability as the melee/weapon users, one of the big flaws in DoTA imo, once the mage got rank 5 icebolt for 600 dmg thats it! while the melee blademaster can keep upping his attackspeed and dmg.
I disagree whole-heartedly. Many of the advantages of the spellcasters is indeed not the damage output, but the disable powers. The ideal is that they are nukers in the beginning but still useful endgame as a result of their ability to stun, slow, silence, etc.
What this means is that a team full of casters is an early-game powerhouse and late game snooze patrol this is true, but then again, anyone try and play FF1 with only white mages?
Now i'm not saying i'm against this idea, but I also don't believe it is as "required" as Sevenix thinks.
