I can agree with this which is why my big talking points are always cc prevention (purify being broken) and class base kits. We have a mode that heavily incentivizes CC. Maybe the dev team didn't anticipate this, maybe they thought Purify would be more effective, maybe they didn't calculate the absolute zerg rush a 3 second stun could result in for a party of people somehow, I don't know. But with that knowledge we now have glaring gaps in the kits of several classes where they have to basically stay out of range and if anything breathes on them wrong they die. This is amplified by the lack of proper communication tools with the rest of your team and being able to do premades where some classes could shine if given the proper support.
SGE can do a ton of dps but I can barely shield my party half the time except for in bursts and it really sucks having zero way to assist the party with any CC or other skills when classes like WHM have so many passive damage/protection skills and cc curation and stun. Needless to say I don't think CC should be "removed" but the current iteration should not allow for a specific tank to just steam roll people because they can, at range, stun, leap in, and destroy and if the server eats the purify they'll get stunned again by the rest of the party. Focusing on targets and stuff I get, but if I were playing WHM not only coudl I purify I could divine veil myself on the retreat, giving a huge edge on pressuring that class at a basic level.
So at this point I just want more CC for more classes and/or balancing the CC to allow for more skill play instead of just zerg rushing everything with classes that can cc with reckless abandon.
When I sit down and think about it, if it wasn't for the cc spam, I probably wouldn't have much complaint about the systems outside of minor tweaks to classes. But man when you look at a GNB to a WAR, or a SCH to a WHM, it's very obvious which one will perform better. People see those big numbers on GNB and think it'll be OP or balanced because it has more burst but you can't burst when people can walk away from your LB, your biggest hitting skill is dependent on being on top of people, and you can't tank if there isn't a tank on the other team lol. Big dps means nothing if someone can literally just...lock you out of doing any dps for too long.
Having beat my head against the wall trying to find a way to make GNB work I agree. Especially when matchmaking (trying to anyways) puts one tank and one healer as much as it can which results in a GNB vs WAR and WAR can just roflstomp a GNB unless very specific conditions are met.
