Good groups are hard to come by, try your best in all forms of content like expert of 50 dungeon roulette to practice your art. The game is designed to rely heavily on dps, its just the design choice SE went with unfortunately, very few types of content reward heal only play style, like any job in the game you just need more practice at dpsing. That's all you gotta do, practice. As i stated before, as long as you don't make excuses and you try, your alright in my book.
Sorry if i am late to the party with the following statement but i have been reading pages of what feyona had to say and this is my response.
Do not constantly use emotions to make points and fling the victim card around(don't pretend you didn't do this either), i can only imagine what you would be like in game if some offered genuine constructive criticism to you. Your behavior in this thread hasn't really been stellar, you should really try to learn from your mistakes in this thread and acknowledge what people say more instead of constantly pointing the finger at others, yes there are arse-holes who only want to hurt you or make a fool of you but you just gotta deal with it like an adult and make your case in a mature manner as possible. If you don't, even if people agree with you they won't come to your defense out of embarrassment, you don't make your side of things look good. In fact you end up hurting your arguments rather than helping them. On some level you need to gain the respect of others to get them to listen to you. IF you want the perceived hate to stop then you need to give them something to respect, whether its on the forums or in-game.
You seemed to come around somewhat in the last few pages, but in the end your behavior overall needs serious improving, if you acted this way in the forums what would you say and do in game? Everyone has a chance to explain themselves on the forums, everyone can carefully write out their thoughts and be be more mature. Not the case in game, i notice in a lot of toxic parties that people will single out your mistakes because they don't like personally you, even if other players in the party has had made mistakes, even serious ones that wiped the party.
