I wanted to make sure because at one point Morrus was referring to strongholds as a feat, or possibly that if you built a stronghold, you got a feat. I never quite understood it, and it's entirely possible I misunderstood what he said (I think this was when the Warlord was being previewed). Or perhaps at that time you were thinking about strongholds as feats but decided against it, seeing how the strongholds preview doesn't use the term. And since feats as an alternative to ASIs weren't listed in the playtests, I got confused and thought they'd be given out a different rate. So, thanks for clearing it up!
But hmm, if there are feat chains--I think it was suggested that they'd be three feats long?--and those "multiclass" feats require you to be at minimum 6th level, you're not going to be able to get all three until 16th level, if you only take feats and no ASIs. Looking forward to checking them out and see how they stack up to ASIs.
