They don't. The use a small number of their favorites and ignore all the rest. Some might be more effective than what they do use but they've never looked into them far enough. D&D 3.0/3.5 and Pathfinder both have this problem when characters hit the mid-teen level and just just gets worse farther up.

+1 for Pathfinder (the first and only edition).

+1 for Starfinder Starships, a mechanic that was advertised as a selling point of the system before it launched

+1 @WatersLethe. I am glad Rob listed it first. I hope it stays that way.

I am less excited about this since I believe it is linked to Campaign mode.

I am more looking for something I can use in Org play to track Space combat.

That might still work with it linked to Campaign but I am unsure since I have barely touched that.

+1 Pathfinder 1e, with 3pp (Community Pack & Spheres of Power/Might),

As a relatively happy PF2 GM, +1 for more Starfinder and Shadowrun 6 support.

I am totally content with HLC for my Pathfinder 1st needs until HLO is mature.

A lot of these are going to be effectively passive buffs to prerequisite abilities in play. For example, the Legendary Vigilantes stuff has lot of things that add extra functionality to Spring Attack, Whirlwind Attack, and Vital Strike, as well as various talents that give you a set of the Improved X combat maneuver feats, and Spheres of Might has various talents like 'whenever you successfully grapple, you also deal damage' and 'whenever you attack with an attack action, you can also attack a second creature at a penalty'. You could pretty easily make a character out of all that that just focuses on 4-5 primary gimmicks and combines them in different ways, with maybe a reference sheet for yourself to keep track of how they all stack.

That doesn't reduce the character's complexity in the Hero Lab context, though, since you've got a bunch of things all adjusting the numbers of other things. A wizard, by contrast, could have about the same amount of actual in-play complexity, but less bother to compute since spells are more self-contained and mostly just need an adjusted DC for each.

I don't know if there's any community voting involved in what the next big thing will be, but if there is: please make it the shared stash. That functionality can be used by all systems, and it would be (in my opinion) a great way of actually making use of the 'online' part of HLO. Being able to 'cast a spell' and have HLO sort out the effects on everyone (no more manually adding conditions, yay!) as well as being able to prepare 'loot' that can be handed out after every scene, will not only be very useful, but will also be a concrete display of the benefits of being online on HLO together.
