Monthly letter practically says nothing:/
BUT
I really hope for some good improvements to the game by autumn since the game is usually pretty dead in summer anyways.
Concerning the achievements (i will only talk about pvp,coz in my mind pve achievemnts already exist anyway in form of loot,and killing a zillion mobs to get some achievemnt has already been done anyways in early khitai)
PVP achivmentss should have world pvp and tournament pvp.the best way to go, is look at the vanity armour in plentty of variaty...that will not bring any unbalance to the game at all, more of a fashion show. and for braging rights there should be a table + more statistics so that support classes will have more interest of doing their bit rather than just k/d whore in 90% of the time...But as far as i understand this is easier to do with set plays like minigames. So achievements in open world pvp are harder to executs,but iam sure there plentty of ideas for that in some threads of this forum.
And last,as someone already said above, ranger needs a overlook, no fun in playing that class at all...as for any dps class ranger should require skills from a player to obtain good dmg,not just gear and 1 button abilities spam. I will repost my old thread on ranger tweaks sometime soon.
@ devs, keep working, u still have 2-3 months untill summer slack will finish,but the chnges you make will have to be good to attract at least the old crowd back. If u achieve that,then the newcomers will join in numbers...
