I'm going to link my old concept for Oberon that has been archived now so people can read over the entire topic, I'm not suggesting the entirety of my concept to be used just a fraction for the upcoming rework.
Would be nice if some of his abilities were combined making space for a new 4th.
1st Combination his passive with Hallowed ground so players have more control over when we want to make friendly pets.
2nd Combination is Renewal with Reckoning that way it doesn't matter if it doesn't scale up, the reason is because on a high level mission you won't do much damage and you will be much safer casting a Renewal that crowd controls enemies around you reducing the risk of you being downed as you make efforts to support your allies.
3rd Combination Hallowed ground and Reckonings crowd control upon cast
The combination would improve him greatly and remove the debate that he is trying to be a bit of everything, the 4th ability I'm suggesting is Paladin theme focused while the rest of his abilities seem a bit more on the Druid side.
The rework we've been shown still doesn't fit the Paladin theme ... Perhaps as people have debated he is a 'Paladin class Druid' but even with this rework he is still just a Druid ... I feel my 4th ability concept really cements the Paladin element.
The extracted ability from my old concept that could be used as a new 4th ability is ...
Divine Olifant (15m, 20m, 25m, 30m Taunt Radius)
(Toggled ability with energy drain. Oberon selects and summons a Divine weapon immobilizing him for 3 seconds whilst taunting all enemies in radius during the weapon selection, after the horn has been sounded Oberon is granted a Divine weapon set. Each set comes with a unique shield that gives Oberon enhancements, all 4 weapons use the same attack combinations but the attacks and animations are varying dependant on which set you are currently wielding. For example one set could have precise slashes and another may have brutish heavy strikes but the combos remain the same to avoid confusion.) https://en.wikipedia.org/wiki/Olifant_(instrument)
Oberon sounds the horn to summon one of his four divine weapon sets whilst taunting all enemies within range.
