How exactly are you guys' habits for manyu collection & character capacity? I've seen that capacity of 100 is recommended, and that upgrading should be done using 10 manyu together for gold efficiency. Following this, I'm now having insufficient space waiting for 10 of the same manyu type. We have a total of 12 types of manyus (4 types x 3 levels), say I have 7 of each, that would occupy 84 slots already.

Is it considered a waste to expand beyond 100 capacity?
