To add, reach weapons (glaives, bardiches, longspears) have some of the best items and enchants on them, especially for mounted characters.
Figured that much. Bardiches seem less focused on charging, but some good glaives and longspears.
Which to Focus in? Decisions, decisions.
There is really nice glave in end game that does 6d6 estra damage on charge and summon a demon if (lol) you kill the target. Insane.
A decent heavy pick with much less damage but debuffing target saves.
And there is a warhammer in act 4 that turns target to stone with a high DC till the end of combat, tried it a bit, ridiculous. Also if you hit the same target again and crit it aplies to aoe
And there was a fauchard that gave spell resistance on charge, not that useful imho.
Edit: I rolled with classic scimitar and shield bash build. 7-8 attacks on a charge, all of them got mythic charge bonuses.
