unified rules vs creature / class feature

[arkhayne]

i'm finding more and more variation of attack of opportunity
on different creatures and i find it increasingly difficult
to think we won anything by replacing the AOO unified rules by a myriad
of variation that are creature dependant (AOO- fighter vs scorpion sting - giant scorpion not the same but really close yet different enough passe for an aoo but with different rules)

the game feel like a miniature combat game with all the rules on the models cards rather than a strong flexible unified rule.

the back order action in doomsday dawn feel exactly like mini combat trick
cool but its a roleplaying game so player doing the exact same act wont get the same result its a miniature proprietary move ...and it feels wrong

I know DD5 has lots of reaction/ actions that are tied to specific creatures but honestly in most case its a sad mistake we should not repeat
its not simplier nor does it bring faster combat resolution

its the polar opposite of what has been done in 1st ed , bringing nothing but a miniature combat flair ( its a nightmare to have to check and recheck every special move on every beast you pit your players against)

Scorpion Sting wrote:

Trigger A creature moves from out of the scorpion’s reach into the scorpion’s reach.

Effect The scorpion makes a stinger Strike against the triggering creature. The scorpion’s multiple attack penalty is not applied to this attack

ATTACK OF OPPORTUNITY wrote:

Trigger A creature within your reach uses a manipulate action or a move action, makes a ranged attack, or leaves a square during a move action it’s using.

Make a melee Strike against the triggering creature at a –2 penalty. If the attack hits and the trigger was a manipulate action, you disrupt that action. This Strike doesn’t count toward your multiple attack penalty, and your multiple attack penalty doesn’t apply to it

It's different enough to be a separate ability, and looking over them and other Reactions I'm not really having an issue with all the variations (in no small part because AoO is the name of a specific ability rather than that type of ability in general).

Going beyond Reactions I'm 100% in favor of Monsters having unique special abilities, it makes them fun, rather than just a bag of HP.
