Theyâre not going to do triple the dps, but they sure will do more and the pulls will grow. There are places were you canât due to interrupts, but in many others there is little to nothing to kick and tank survival is mostly about kiting and not get debuffed by mobs, so expect to see things going more in the direction of bfa 2.0
The two things go togheter, you need to consider the aoe cap when balancing and viceversa, they are not two sterile things that donât interact.
If you have ability A uncapped that does X dmg you canât tune up ability B that is capped to do the same overall dmg, because to keep up with A scaling with targets, B should do ludicrous dmg to the point of being a balance issue when used on a small amount of targets.
And on the opposite side, if B dmg is your target, you can tune A to do the same dmg over a lot of targets, but at that point, A will be undertuned when the target pool is limited.
The aoe cap is definetly no fun, but it can work as it is when you have an unequal distribution of the cap between classes and specs.
