Why not go 6IK + 2 Wastes, run Furnace/Lamentation (2 rend stacks)/Convention of Elements in the cube and then play Rend + Charge/Whirlwind. It's a much stronger build than Hota for soloing anyway due to superior AOE damage and better survival.
HOTA is only really best in groups due to group synergy, the big crits are used to set off exploding palm (thus taking care of the AOE damage requirements) while the single target takes care of the rift guardian.. Survival not being an issue because you would run with a healing monk.
HOTA is just the ultimate group spec, both Rend (6 IK/2 Wastes) and WW (6 Waste + 2 BK) are stronger solo.
