I feel like some people on this forum need to review what homogeneity is. It comes up an awful lot in nonsensical ways.
Hybrid pet builds are a weak point in the GD build spectrum, I freely admit that we did not hit the mark with that play style and realistically probably won’t at this point in the game’s life cycle.
Are hybrid builds viable for most content? Sure. Will they be setting records or make the list for endgame suggestions? Unlikely. Could the issue be addressed at this point? Not without some serious review and likely undesirable repercussions echoing across other builds (Cough Bane of the Winter King Cough).
We’ve heard that opinion about pets and sets for a while, so we are taking steps to reduce the impact of sets on pet builds with the next update.
This will largely come by taking some of the power pet sets provide and baking it into baseline stats for pets from all sources. Bonuses such as increased summon limits for the non-skeletons in the room will remain the domain of sets however as that much power simply cannot be on a single gear slot, history has shown that gets out of control fast.
Baking increased summon limits into the base skills could happen, but not without significant rebalancing, which is ill-advised at this point. It would not be as simple as cutting the base damage of those pets in half as anyone building pets knows well that each additional pet has major implications for endgame damage scaling. Not to mention that halved damage would be undesirable for the leveling phase.
Maybe consider for a moment that those stats are not budgeted the same way on pet items. Some stats are there as a bonus, not taking up stat budget from “more desirable” bonuses.
