Hey guys, got back from RCB5! I found a few things:
-jab is actually amazing, especially if you space near the tip to repel.
-Usmash is officially more useless to me than DT (every good player avoids it and punishes, and if they are on a platform, they just shield, drop and punish while the usmash is still in effect).
-I actually used DT for a few good things (RDT, and killing a slow tilt a few times)
-Dsmash is actually pretty good, as well as ftilt oos.
-MK's ftilt will kill Lucario's fsmash unless you space it on the minute tipper (otherwise, he'll just walk ftilt to kill).
-Ness' fair is no fair.
Now onto the jab, and sheik ftilt discussion:
DI?
dair?
much better spacing and outranging?
and no kill till like 180% = scary lucario?
On jab:
I've really enjoyed this move in my tourney. it restores decay well, has great range, decent knock back (especially after the occasional FP or grab). It also works well on ppl who rush in after fsmash, expecting a laggy lucario to get punished, only to see jab after mindgamed jab again.
