I think what you're suggesting for chainspell dispel is substantially what already happens with chainspell stun. The rdm/drk will rip hate off anything and everything, and it's typically only the fact that the target spends most of its time stunned that keeps it from snacking on you. (In some cases they manage to do something anyway; I've eaten flares from Suzaku while chainstunning him during his own chainspell, for example.)

Although it's possible that stun decays more, and it's only the fact that the stuns are all done in rapid succession that pushes them up to such a ridiculous hate value.

In any case, if this does become abused somehow, it would be simple to fix: greatly lower the enmity of dispels that don't dispel anything. Then you can't cast 32 dispels for full hate unless the target has 32 dispellable effects on (not bloody likely), but the enmity of dispel in ordinary situations wouldn't be affected (you're only going to cast it when you expect it to have an effect).

P.S. "Non-decaying" hate is somewhat misnamed: in real fight situations, it will still be reduced when the monster takes a swing at you and does damage or removes shadows (the part that is too complex to easily see by this type of test). So the hypothetical dispel-tank would also need to kite and consistently stay out of range/never have their stoneskin broken to maintain hate (/nin wouldn't really help because, although you might stay alive by using it, you'd shed the hate you 2houred to build). Regularly renewed spike hate can be just as important as "permanent" hate over the long term when hate is being lost to hits faster than it can be lost over time.

While this information *is* useful, don't try to apply it beyond its actual applicability. The test scenario contains several simplifications not present in the typical real fight.

P.P.S. It's unfortunate that their testing methodology requires illegal hacks. Maybe there's some setting where distance can be calibrated by other means (tiles on the floor?) that would allow non-hacking players to contribute data?
