Why I miss Season 3
My builds for Wukong in S3 are as follows
(cant think of item name but on activation made your next 3 attacks crit) 
(40ar & 40mr)
(merc or tabi)
any boot
Lifesteal builds, full tank builds with ravenous, critbuild, and many more viable options
Mainly took flat damage marks and quints with scaling armor seals and scaling mr glyphs, but also took arpen marks and quints on occasion for squishies)
These are bruiser builds that allowed me to dive the entire enemy team with my ult and survive long enough to channel the full duration while while doing about 60% of their squishies max health (killing the one that took the EQ after about 1-2 seconds of ult)
Currently, the only build I use now is

I'm basically playing a full out assassin melting squishies from invisibility with EQAA and then using R to escape. I take Electrocute and 10% CDR.
While it's still fun. This is not the Wukong I love to play. Talon and Fizz were my go to options for this.
Technically I can still pull off

for off tank if my team needs an engager on the frontline but it makes me 100% team dependent and carrying becomes a chore. But I build towards team needs more than carrying.
In today's League the options I have to build a viable Wukong (who is an extremely flexible champ) has become very limited.
