That's not what's happening, supposedly.Do you kill equal lvl mobs equally easy on lvl 60 as on lvl 18? If you did you could use blackened defias leather for the entire levelling race ;)
That feels wrong to me. At the very least in the same gear your stats vs. same lvl mobs should remain constant as you level up. When added with the fact that you are gaining stats/talent points as you level, mobs of the same base level should be getting slightly easier, not harder.
Making them harder is just a fucked up attempt at overcompensating for mudflation.
Various rating abilities (crit% being the most important one) are apparently based off of the character's level (and not the monster's). So when I level from 60 to 61, I'll gain 1 talent point, no new spells, and lose crit rating. Technically, I'll gain hit% to the point where I'll always hit... which wastes even more points from my current gear.
To give an example - I currently have 10% crit from gear. After leveling, I'll have 9.2% crit from gear, with no gains from anything else.
This change does zero by the time people finish leveling. When we hit 70, people will have about the same crit percent that they currently have. All it does is quickly outdate level 60 gear... surprisingly fast if reports are accurate.
It is somewhat different for casters. We gain by far most of our damage increase from spell damage. We gain very little from INT and have lower crit rates too.
That actually hurts us with the current itemization formula since having one mod stacked costs more than spreading out the effect over multiple mods. Hence the caster complaints about itemization. However, it will help us in the expasion. Frost mages can have 11% to hit and arcane 10% from talents alone (which dont scale down). So we will not miss much by having little to hit on gear. In PvP, to hit on gear is outright useless. By the same token, a frost mage is not very crit dependent. Very few if any frost mages stack crit on gear.
Thus, this change will have virtually no impact on frost mages. It will have more impact on fire, but still a lot less than on say rogues or warriors. I guess that is payback for having had crappy itemization (we didnt even have a to hit mod the first 9 months) for the longest time.
