Thanks for playing and feedback!
If I am to make new skills which infect TFs to other party members, I would add some benefits to them, basically making them magic skills which spend other members' MP instead of the user's. This way, such skills can be used even by "serious" players. But I feel that designing such skills for every monster would be too much work, so many monsters would receive generic ones or none at all.
If your point is a simple "this game's TFs need easier accesses", I agree - it's sometimes hard to get TF'd in this game.
I'm not adding a toggle option which impacts effects of actions or difficulty of the game. If you don't want your party members to do MP damage, just choose skills which don't involve it.
Also, if TF'd monster's skills are too unfavorable, just don't get TF'd - Once you reach the end of the Forest maze, trigger the message but don't go further immediately, use Orb of Wings to return to the Tavern and remove low-MP adventurers from the party, then go directly to the boss battle. This game will be balanced around this strategy. At least I will make it clear that you can teleport to the boss once you have reached there.
