Im reading this forums a lot, mostly topics related to new expansion, and what i saw the most is sentence "stop fixing what is not broken". And i was :O
Lets take a look at our classes atm and see if they really are so good as you guys claim they are. Turbine said they want us to feel the trait lines from the start of the game, lvl 10. Atm however i one out of 3 lines is locked for us until moria basicly, and we cant feel that difference between those lines. Lets take burglar gambler as an example. To have fun as a gambler you need Lucky Strike, blue legendary, and maybe gamble chance legacy or you are just highly nerfed QK burg. There are other classes that are waiting for usefull traits from some trait lines to the levels 40+.
Another fact is: Most of the players are traited always with same traits. They dont change it for months. Champs, hunters, burglars... Even when you have situations, for champs for example, where they can trait for some aoe, they will still stay in red line and just use a bit more aoe skills. This is broken, imo. Even when you are forced to retrait, with clases like RK, once for healing once for dps, you always select the same traits you had last time you were traited that way. You will select same 7 traits for lighting line that you selected last time when you have been dpsing. And you call that customization? Some traits are useless and some are not. You will just fill the spots with same useful ones that most of the people use.
You may ask me if this will be the case in HD.. It will be. Difference is, now you will get skills tied to each line and you will need to adjust your skill rotation, or actually use completely different skill set with this line. I think most people just want to keep all the shiny stuff they have and change lame skills for more shiny skills. I dont know why does champ need all that bubbles, dire need, bracing attack and adamant in single target dps line. If he is playing correct, as well as his fellows, he should not be hit. At all. Instead of that give them dps enhancing versions of the skill. If you get aggro, you screwed up, and you deserve to die, because you arent playing good.
Lets face it, some traits we are not using at all, even some trait lines (blue LM, yellow hunter) because theyre broken. Changing trait lines usually just makes 1-3 skills more/less potent and thats it. We just slightly have to change rotation and thats it.
One more thing i would like to speak about are "oh ####" skills and selfheals. Only classes in need of those skills are tanks and healers. If you screw up, you get aggro as dpser, you stand in wrong position, you dont cc something, then you and your fellowship has to pay for this, with wipe if its bigger mistake.
People saying they dont want to learn classes again are making me facepalm too. We are playing this game for fun and we need challenges and new stuff to make us entertained. I saw many complaints about not enough content last two years.. Now turbine is giving us new tools that are offering us testing and exploring new versions of classes, giving us entertainment for months, now you dont want it... just omg. You will have to learn new instances, how they work, what to do etc. How is doing same thing with classes so different?
Just take changes and adapt, and if you dont like it, or if theres somehting broken, then its time to complain. Atm you have no idea about how classes will work, especially because dev diaries give zero information.
