Weird suggestion, but it may be worth deleting the... 18th column, I guess? Y'know, summoning in its entirety. I've always thought it was more of a method of filling niches than a niche in and of itself, ever since the original original thread. Might require more thinkery than more standard, "Alter this number," changes, but it's worth considering. As is, the system kinda double counts stuff like meat shield, battlefield control, or even occasionally healing or domination. Y'know, all that stuff that summoning does.
