1. All I can say is learn to adapt or quit complaining. If it was all PvE then nobody would care that Paragons were highly overpowered...ok so not "highly" but they were overpowered, so are Dervish in my opinion. This means in the PvP side of the game certain classes unbalance the game. Is it a shame that PvE gets hit by the nerf stick too sure...but as I said learn to adapt. Seriously people complain as much about the Paragon nerf as they did the gale nerf, or the SF nerf (though less complaints and more rejoicing, not that it did alot anyways 15 ene cast whoopdie-do
)
2.a)Chests: its a gamble and thats the whole point of it. A-net meant it to be a gold sink NOT a boost for poor players. If you can't afford keys then don't open chests unless you get a key from a drop.
b) Items: First off anyone who thinks purples are useless needs to uninstall. Sure getting a gold is better, but I have found max mods on purple items. Wait whats that I just made 20k off a max sundering mod I salvaged from a purple bow?????!!!!! ZOMG so useless. Sure its rare and usually it isn't the mod you want, but it does happen. Which brings me to the point that you say out of 100's of chests you've gotten 2 good items. You ever think maybe to salvage parts off 2 of the other items and slap them on a 3rd one with a low req? Consider:
i. I open chest and id a gold bow its req 9, 15-stance, 2 crap mods not even max, say a 3:1 vamp (which on a bow sucks) and Armor +4 always.
ii. I open chest and id a gold bow thats req 13, 14-enchanted, 20/20 sundering, and a bow grip of marksmanship +18%
iii. I open chest and id a gold bow thats req 13, 13% vs undead, +30 fort mod, and no bow string.
iv. See where I'm going with this? Salvage the +30 fort, and the 20/20 sundering. Then slap them on the req 9 15-stance (or wait for a low req 15^50 or w/e). Point is just because individual items may not be all that great you can generally make one "good" item out of 2-3 "ok-bad" items.
c) Greens: Not much I can say, the point is for them to drop rarely so that way not everyone and their kid sister has one. If you're complaining about only getting crap greens, then don't farm for the crap ones. Not alot you can do but farm or pay for it.
3. This is really the same as greens, prices are based on supply and demand. If you don't want to dish out 30k for a sup vigor then quite simply don't. Dish out the 5k for a major and live with the -15 health or whatever the difference is.
4. Storage: Finally something in all that I can agree with. Though personally I think they should charge more than 50g for it....
