eli5 col please

fill the tents first okay..

1. my ssanctuary and medical tent capacity is only 100k at the moment. do i need to send only 100k or less troops to reinforce the spire or hall, or can i send a full 150k march of t8 troops?

2. should i keep summoning troops back from the sanctuary (using either diamonds or holy light) and continue attacking spires or reinforcing to gain points or is this not worth it using diamonds?

3. so what is the points obtained via killing enemy units that gives 100 points for reaching 150k kills or is this just extra points? so just kill t8 troops 500k and you get 10k points + 100 points?

4. regarding trading kills, i send 100k t8 troops to tiles, the enemy kills them, the enemy gets kill points, and i get death points. then, i heal the troops from the sanctuary and send them again to the tiles until you reach 12k points?

if i have missed anything, please let me know. ty
