One of my players was reviewing the path abilities a Champion gets and he found that at low levels and low tiers, interesting choices are limited.
He was saying that if you got a mythic tier at every even number level, there are few choices that are interesting. At level 2 and tier 1 he would probably choose To the death. At level 4 and tier 2 he wasn't sure. Precision is only useful at level 6 and than much later at level 11. Always a chanceisn't bad, but it a situation that happens rarely. Armor Master isn't very useful for a fighter or paladin unless you take it multiple times, so it feels like wasting 3 path ability to not get Dex penalty when wearing a full plate and with all the more interesting abilities unlocking later, you'll probably never chose it 3 times.
Aerial Assault, Devastating smash and Wall smasher are interesting if you like to use combat maneuvres, which we do not use often. The universal abilities are limited too if you do not use skills a lot. All that was left were Fist full of daggers and Stanch wounds for tier 2 abilitiess for a level 4 PC. Same happens for a lvel 8 tier 4 PC. He felt the lack of options would mean that a lot of PCs would always chose the same abilities and look similar over time.
He suggested that Champion and Trickter get a path ability that let's you select a mythic feat instead, Extra Mythic Feat, probably from a limited list depending on the path. Champions could have access to: Acrobatic, Athletic, Blind-fight, Cleave, Combat expertise, Combat reflexes, Dodge, etc... You get the idea.
