Feels a little hostile and missing the point. As if you didnt read the post. I play DPS and I play Tanks, and dabble into healing as well.
When I am playing the different tanks, the gameplay loop of builder/spender to keep up an active mitigation to live, just doesnt feel compelling to me. Its fine. But, after tanking a few keys or a raid, I need a break and want to play a DPS. And at least the reason for me is that DPS specs just feel a lot more compelling to play. Its fun lining up burst windows, and using the different DPS synergies that rotationally happen with specs.
DPS feels objectively more fun to play to me than a tank. And I do like tanking. But, it does get boring after a bit to me, as rotationally there doesnt feel like there is much depth. Spam builders, keep active mitigation up, rotate CDs for damage events, stun/interrupt. There is a lot of fun with rounding up pulls, positioning them and setting the pace through the dungeon. But, the actual button pressing and ability usage? It just feels dull.
