And as far as "restricting to only one class" by having these limitations, I disagree. I mean not everyone wants to play certain classes, and the achievements reflect on getting a relic weapon on each class, but only one animus and one novus. Getting multiple doesn't matter achievement wise. The game is built in a way that you can get any job geared up rather easily with ilvl 90 myth items and unlocks all endgame content, but if you don't like that class you can have the class you prefer to be the one you spend the most time on. It's made so you can try every class and then when it boils down to it, do the harder endgame content as the class you prefer because you want to perfect that playing style and get further. Jack of all Trades, master of one is the idea. If you really like playing all the different jobs, power to you, but the end game content is not easy to pass, so you'd only really want to run it on a job you feel comfortable with.
