interesting... pointless SA huh... you are using 4-5-1V i am right ?
"4-5-1V needs excellent DMC and AML/AMR players to work correctly. It's my default formation, and the only arrows I use are 'up' on the two AM players."
Your point? 4-5-1V doesn't use DML. It doesn't use ML either, hence I have a reasonable-Q utility ML/DML for the occasions when I do need one of those positions.
Any formation or tactics advice given is based purely on experience with my teams...
