Which cross class abilities should i get for Machinist?

[Zophar]

SS is only for GLA/ PGL/ MRD/ LNC/ ARC/ ROG/ BRD

Well golly skippy.
Raging Strikes, Quelling Strikes, Hawk's Eye are GLA, PGL, MRD, LNC, ARC, ROG, CNJ, THM, ACN, BRD, BLM, SMN.
Invigorate and Blood for Blood are GLA,PGL,MRD,LNC,ARC,ROG,CNJ,THM,ACN,MNK,DRG,BRD,NIN.

By your logic it looks like MCN is just hosed out of all cross class abilities. Does this sound stupid to you? God I hope so.

Please note straight shot may not actually be cross classable - it is only usable by base classes (DoW classes for that matter), not jobs (excluding bard).

That is because the only "jobs" that cross classed arc up til now have been casters. No caster has access to ANY physical attack cross abilities(except for Mercy Stroke for some odd reason).

Inversely, SS is crossable by EVERY single physical attacker, excluding jobs, because, as mentioned, no physical job can cross ANYTHING from arc
