To an extent, yes, ultimate summons are practically paid-only. Worry not, though, because Witch Hunt isn't actually that useful unless you max out your stats, which you can't achieve until you're at a point where you won't need Witch Hunt.

What you're looking for is an active guild who will help you with archwitches. There are many guilds out there looking for players who frequently send requests for reinforcements.
