man people really hate rokien. He's got an opinion just like everyone else. he's just a bit more...batshit crazy about them.

anyway.

It's been stated that there will be 3 main story arcs. and i have no doubts that eventually there will be more. you can easily balance between leves/trash quests, story arcs, and grinding to get 3 50s.

all in all, i don't think getting every single class to 50 is for everyone. I personally like versatility, so i'd like to have one class in every role, and also level classes i enjoy at a more leisurely pace. at some point i'll have to pick a main class to gear/pimp out.

right now I have WHM (support) BLM (ranged DD) MNK (Melee DD) and am working on WAR (Tank) so i can fulfill any role needed. I have yet to decide which class to focus on first, but i will primarily be gearing with GC equips, because they will be useful on multiple classes.

It's really about how you want to play. They've made thread about rare rewards for solo content. they've said there will be 3 main story arcs. and they've said they will add in trash quests. open world grinding is also implied to be viable, just not the most effecient. if this is delivered, the game will be very versatile. there will be rewarding solo content. you can level at your own pace (grinds, trash quests, story quests) and the classes are being revamped, I assume to help further differentiate them and make them even more fun to play. there's nothing stopping us from exploring on our own. there will probably be XP rewards for this as well, if they are truly following the mmo standard. not to mention they are also revamping gathering/crafting to be more interactive and less boring. so really there should be something for everyone.

so we can speculate all we want, but it's really up to the delivery at this point.
