Siege server is empty alot now.
I started leaving when big clan stacks on, not just because unlikely to get decent multi but also because constantly running solo into hordes of clanmates at the important part of maps, ie flag, gate mechs etc gets dull.
I know some people say they like to fight alongside clanmates while on ts, personally I always found fighting against clanmates on TS far more fun.
Strat is basically dead because big clans got too powerful and efficient, all credit to them but lets not let the same happen to siege as well.
