I think its lack of choice in the endgame thats the problem really. When it comes to SC's, you currently have the following choices:-

1) Tartarians.

By a long and clear margin. Nothing else compares really. You will often see a dozen+ tartarians in the endgame. Abominations, poison golems, iron dragons and tarrasque are just not on the same playing field in terms of power.

2) Beyond Tartarians you have wish + GoR, as a second rate hugely expensive option. The Seraph is the most popular choice for the wish but again thats only through lack of choice because nothing comes close to it in terms of power. Even then, its rare, very rare to see a seraph in the endgame.

The best solution would be more endgame choice, the introduction of some new SC chasis that rival the power of tartarians/Seraphs, preferably in other schools of magic, other than death/astral. Those should be normal summons castable (with the required paths in magic of course) by any nation.

This would make the endgame more diverse and fun.
