This is a bit of an Oxymoron though…
You prefer something simple, yet whack a mole is also simple?
Which one is it?
Whack a mole where it’s unpredictable what will come up next is not what I like. Arms in WotLK was predictable. The only proc was Overpower and it happened every 6 seconds.
Sudden death was wotlk and is basically the grandfather of all modern rotational RNG procs.
Static rotations aren’t coming back anytime soon design wise nearly every spec has a few reactionary procs to deal with.
Arms isn’t really that unpredictable at all when you get to it.
The main proc all builds have is Tactician.
Optional gameplay altering procs in Sudden Death which is mostly raid use only potentially slayer m+, Exhilarating Blows for M+ builds for both Slayer/Colossus to get more cleaves out in Merciless Bonegrinder windows and Battlelord which is an optional pick for Colossus M+ ST taking a point of bloodborne.
If anything these additions help make the gameplay a little more engaging and you can even turn your brain off while playing with them assuming you’ve set-up an easy to understand UI pack for yourself or picked one of the many ok options from wago.
