You didn't class having every single class maxed in Vanilla/TBC as hard work? Right. Unless you're only including RaFing during TBC, in which case I take it all back.
Sure, compared to old-school MMOs it's a walk in the part, but it's still weeks upon weeks of consecutive grinding. Which, in today's terms, is bloody hard work, seeing as how you can get full epics while AFKing in LFR.
This is true especially for heroic raiders. They try the bosses over and over again. May take a whole day but eventually the practice helps them learn the fight to a T. Some people yes are slower at this, but unless you have actually brain in capabilities. You will learn it without even trying by repetition.
if people don't realize how a class is played by level 20, they likely won't do much better at 90+.
Seriously, it's sad how people still think you need to level a character to figure out the 1-4 ways to make the build work. This is a game, not rocket science or brain surgery... it tells you what to do when you look through the in game menu or if you ask people in game nicely and have a sense motive modifier greater than +2
Progress is someone developing skill from X standpoint by repetition.
However, X is different from person to person - Rendering each person not equally skilled in all areas, because they are not on equal terms. Some react faster, some think faster, some perceive information faster..
These are facts. I do not like to repeat myself, throwing definitions at something does not create arguments. No amount of semantics invalidates the point i am making, and the flaw of your said argument.
This is why I enjoy leveling a character before end game. You learn the class very well at a good pace. Rather than learning all the abilities at one time.
Yes lets give players another reason and way to be nasty to one another, just what we need! ... nope.
Lets not, you can feel special all to yourself knowing that you levelled up manually rather than paying for a boost. No need to give achievements and segregate people just for levelling.
Why not just have a "Paid To Win" title meta for those players? Then everyone would do it for the title and nobody would give a shit?
No, it is fact. If you ever went to school you would know that it is fact.
Now I highly doubt you went to school but if you did then you most likely had someone in your class that just knew math, didn't matter if they did their homework or not, they would always get the best grades. Same applies to all classes, for example when I were in school I could learn programming much much faster than anyone else in my class, while they sat in class and had to get help from the teacher all the time I completed my programming assignment in under an hour depending on the assignment.
