Introduction:
I'll start off by saying that Realmshifter is not in a terrible place right now. If we look back three years to the introduction of Avidity and the beginning of the class rework cycle, the game has come a long way. Realmshifter now is better than the Realmshifter that had Avidity added to it.
In 2023 Realmshifter was bad. The class relied on Chained Shield to hit more than a single enemy in endgame content, and had to build as a knock-off Gilgamesh both to deal damage with Chained Shield and to deal with getting hit by every single enemy on the backswing. Towers were really tough - and fairly slow even when you got good at them.
And so, in the H1 balance patch for 2023 Odie handed down a gift: Avidity. Avidity would give Realmshifter a small extra push to better survive encounters and was a cool thief-y mechanic. This was, at the time, not viewed in any way as Realmshifter's "identity". It was a just a little mechanic to help out a class that struggled and it did it's job well.
Avidity
Avidity is a small rng-based utility mechanic. You cannot build around it, you cannot rely on it, and it doesn't enable anything that wouldn't also be possible without Avidity. When Avidity was added, it didn't seem to be meant as a 'class line mechanic' that would drop down the entire thief stack, it was a just an extra thing, it worked great in that position.
This differs greatly from Collateral Damage, Apex, and Flasks. Avidity suffers from being the first mechanic added in what ended up being a cycle of increasingly complex and interesting mechanics. Avidity is not complex and avidity is not interesting. You simply have a chance to get an extra turn on every action, and there's a little bit of gear to boost that chance. That is all.
Avidity is powerful. Never get that wrong. But it's flawed.
Being left behind
Avidity is powerful and must be capped. I've run the math before and increasing the Avidity cap even beyond 30% would quickly run away with the numbers. That is also Avidity's biggest flaw. You can never have a build based around Avidity because Avidity can and should never be a high enough % to build around it.
That severely limits the gear that Northern Forge is able to add to interact with Avidity, and also limits what Realmshifter's options are.
Collateral Damage, Flasks, and Apex all have these things in common:
- At least two independently scaling stats
- At least one stat that can be pushed an unlimited amount
- Multiple builds across content that focus heavily on the mechanic.
Those are class identities. Avidity is not.
-# I didn't include beowulf and summoner in the comparison because those classes function differently overall (followers and summons, respectively) and as such scale and build completely differently.
All of those factors allow those classes to get unique amity bonuses, class ability-specific titan augments, and significantly more gear that is best specifically on those classes.
Conclusion
Realmshifter needs something that scales and can be included across event and non-event gear/augments/amities.
