Hello Segaslah!
How are you? Aleph bombs have their own penalization, as by wasting it, you decrease the benefits you obtain though the talent cards. Also, in missions such as Short Fused, you'd waste your chance to keep up with the mission's objective.
I get your point tho. As antag 4 people aleph bombing can be quite the challenge. Harec, with the stalk ability is quite useful to avoid those kind of situations! Mikahwould be my personal choice to shift positions. Wait till their Aleph explodes and get you back to action as fast a possible.
