It used to be. You say it's easy to find control in the HotA? :D I personally built 6 GM4s, visited 5-6 Shrine level 4s, and a bunch of Dungeons – all with zero results. Reddi also tried to build, according to him, he added about 5 guilds – but no luck, no teleportation... That's how it is, and AA in HotA is just an overpowered artifact because it balances morale :) Another game added to the list of dissatisfaction with artifacts that give negative morale :( Thanks for the game.
A rework in HotA is still needed. Relying on miracle scrolls with control on HL+U is no more likely than getting control magic in Pandoras (which is also quite rare). This is perhaps the most necessary thing that is missing for a complete match!
Otherwise, the version is quite good, I'll write more details about my impressions later, as I've already played a certain number of games and can give an independent assessment:)
