they are at the ToT lfr point, if they cant take it from there, theres no help for them. i give advice, its more then im required to, if they cant at least play their own toon and find their way into raiding well that ones on them
despite what some are claiming its not hard to get into a group without absurd ilvs, granted it may not be a clear group for ToT but at 490-500 ilv if youre expecting a clear you better break out your wallet and be ready to pay up for a carry.
but for the sake of being through ill list it clearly,
-make sure to get mogu runes every week
-find pug groups for ToT or a guild with promise and a opening
-/pray often to the rng gods
-continue to do oon and nalak for 522 world boss loot
-run heroic scenarios daily for chance at 516 epics
not much to do after 490, its the easy yet long because luck and networking capabilities take over whereas the journey from fresh 90 to ready for it is far quicker if slightly more complicated.
