some of the monk/champ skills (OI, combos) become irrelevant once you change into shura;
relying on such single-target skills is very ineffective for leveling; AoE is the way to go;
monk/champ standard build
pneuma is essential overall, while chain crush becomes obsolete once you get AoE skills;
flash combo (FC) is now the most efficient PvM/leveling skill for shura - it's also viable for low-tier MvPing;
manual combo TC is still the most powerful AoE, but that comes with the price of %HP/%SP (30/15 for lvl-10) - while FC only needs 65 SP and 3 spheres (and can be recast every 4 seconds);
snap (gather mob) > windmill (stun) > FC is now the usual chain;
if by "PvM" shura, you meant a (solo) build for leveling (sample order):
FC-5 (job 14)
windmill + TC-10 (job 28)
GT-energy gain-3 + PA (job 33)
RD-10 (job 48)
GT-cure-1 (job 49)
for later party play (as snap puller), CC-5 (job 53) can be great;
this leaves you 7 points at job 60, though that doesn't really mean much if you intend to switch to an end-game build;
a more realistic (w/out super high tier gears) build (for party play as MS tank, and eventually snap puller) would be to go straight to PA + RD-10 (job 26; 27 w/ windmill);
you can then gradually work on the rest of the skills (FC, TC, etc); this should be the faster option if you don't have the gears to make solo leveling viable (as shura is heavily dependent on good gears);
PvM builds do not really need AGI (especially as much as 80 at early-mid levels);
assuming you're currently around base lvl-134 (since you said 80s for each stat except LUK), would suggest removing all AGI and increase STR and VIT (up to 90~100+);
if you have plans to use GFSS+temp boots (either STR or VIT boots), you have to keep INT significantly low (down to 30~40) for the meantime; STR (or VIT) can be at 90, while VIT (or STR) can be up to 120; DEX stays 80~90 for now; from there, work your way up to your final stat build;
mHP (120 VIT) setup is a common entry-mid level choice due to its contribution to survivability in addition to TC/FC damage;
ATK (120 STR) setup is for purely maximizing TC/FC damage for power leveling, and is best combined with high %damage modifiers (w/out neglecting mHP);
