You can easily get to 470 doing msv lfr+pugging it (if you act a bit convincing joining a msv pug with below 470 ilvl isn't difficult). With 470 you get into hof+terrace lfr which easily gets you to 475+, you can then pug hof and terrace and you are at 480, tot lfr. That combined with sha, galleon, oonadasta (these 3 will obviously help the previous steps too) and jin'rokh (pugging the first tot boss is a complete joke) will get you to (or close to) 490. As an added bonus you'll also be able to pick up a 522 piece from valor after at most a week. This isn't an exaggeration or something you need amazing rng/luck to achive, with the 10% nerfs, increased drop rates and close to unlimited coins (the key run will yield you ~15 charms even if you are poorly geared) it's simply normal. This is with me entirely excluding reps, bmah and crafting which can get you there even quicker.
