Did you seriously use "witch" for "which" =P
Homophones are like homophobes, their dickiness annoy and confound me.
What do you expect to do end game in an MMO exactly then?
I am a bit confused now.
Continue questing forever?
Doing /dance in fleet?
BTW do you have all the Datacrons yet? Done all the bonus series?
To be honest, concerning your first question, i dont know. As i said, maybe i´m just burned out. But something along the lines of player driven content as a bounty board or an escrow system where players could post orders (missions) for mats (if they are crafters in need of resources) or place equipment orders, or mail/item deliveries (remove the mail item system!)
All those would go a long way to remove the annoying repetition of the endgame. These days when i log on to my sorcerer i know the drill... go to belsavis do a couple of dailies, go to ilum, do some more dailies, go to fleet and spam chat for an hour looking for a group... oh the fun
Concerning your second question, yes to both. I went for the datacrons as i quested on each planet (something i´ve yet to do with my sage), including the +10 datacron and all the stupidity it involves.
The bonus series i did as i leveled, if i remember correctly i think i dinged 50 while doing the Hoth one.
