I always loved my 15/24, probably not the best but atleast I can win the round when I'm last man standing vs 3 katana spammers (I believe macropus was included there too).
That's not hard. Just run away/block until macropus tk's his allies and then cheer as he gets 5/5
Forgot:
My last pike-focused build was 27/12. Hit like a truck (always aim for the head with a pike btw), although you move very slowly.
My thinking was that the length and weight of the pike would slow me down anyway, so low athl wouldn't change much. Pike is one of those weapons were you either need shitton of athl (8 or more) or kill them in no more than 2 hits (9 ps or more).
About facehuggers: Nudge them or kick them. Carrying a sidearm is strongly advised too, for the Pike pike. Long spear can do ok-ish without a sidearm.
