i have a 5 mixed group at 50, and 2 toons geared for GSB/RoS.

After playing the game a bit and back since Beta 2, i decided to not box for Experts anymore, due to the speed being vastly faster running with 4 other people, albeit that being hard to do on some servers. There are some bosses that will give your problems in experts. ie: Plutonus in DSM on Expert.

Also what grind were you told about? ie: faction/ gear? which then the answer is yes, there is a grind, if you want to call it a grind, i see it as a necessity to build a character in any game, its definitely not a grind like Aion was or a grind like FFXI or FFXIV. Leveling speed is on par with wow 1 - 70 or slight faster depending on playtime, and quest knowledge. 5 Boxing all quests and also doing the instances a few times at the transition point between areas puts you finish up in shimmersands or stillmoor or iron pine peaks, and then that leaves 1 to 2 of the other zones to complete at 50, which is not bad as all the areas are the start of your lvl 50 faction grinding, and doing these quests speeds it up. You need roughly 260 plaques for a full set of vendor T1 Epics, T2 set of epics is much much more then that. By gauging that i got 120 plaques in a few days it doesnt seem bad at all, but i also have a decent guild to run with and im not boxing the experts as i hoped i would be doing.

All in all, the content will be box-able, someone like void is most likely a more efficient boxer then i am, which i have a bad understanding and conceptualizing layouts/keybinds and macro setup to allow me to box better. I primarily box to have more money for my mains to spend on gear and stuff, not to mention making mob killing and aoe more interesting.
