So they introduce more variety into how you spec the character, and that's a 'nerf'?
That's the propaganda line, yes. Unfortunately the change would be so horribly devastating to how combat has run for awhile now, it'd really cripple how effective players can be against mobs. i.e., who gives a fuck about slotting +% to Attack Range when 99% of CoH fights are close-combat brawls?
A way to think of this in a more graspable way, (since CoH is fairly unique in the sub-mechanics it uses), is if Blizzard decided, out of the blue, that Players who invest into one Talent tree would not see returns that grew more and more powerful the more you put into it, but would actually see diminishing
returns past a certain point. In theory, this "introduces more variety" in the sense that you can't just crank your class's best tree and forget about it, but it'd also be a devastating nerf, and actually make characters more vanilla in the long run, since everyone ends up a jack-of-all-trades (with respect to other members of their class).
The way to solve the diversity problem would be to shake up class roles. Look at how WoW did this -- the main tank in the game, the Warrior, can also be a hell of a DPS machine, if tuned right. The main healer in the game, the Priest, can also dish out horrific damage, though it's not nearly as efficient or instantaneous as a Mage. CoH never was built for this diversity -- Tanks were Tanks and nothing else, Defenders were Healers and nothing else, (god helped you if you tried to be anything else as a Defender), Blasters were Burst DPS and nothing else, Scrappers were sustained melee DPS and nothing else, etc.
Thus, why the fuck would you want to 'diversify' something that by its very nature can't be diverse? What use does a Tank have adding +20% more damage to his pitiful attack? What use does a Healer have adding +10% range to his heals -- no moron would ever be that far from a Tank in case he actually pulled aggro.
Ultimately, it amounts to a horrible nerf, as you're pigeonholed by your class by default. Now you can't enhance your class's (very limited) strengths, so you can't even be good at
the only thing you're supposed to be doing.
It's a horribly backwards, meaningless choice that won't promote anything close to 'diversity.' And the doublethink bullshit they feel like spouting about more "variety" is just that -- doublethink bullshit.
