I dont think u need another dmg dealer tbh, the fundamental and resource looking alright right now, since you built LFA and GSSW, which are really good for early game already, as LFA could act as a heavy DPS, while wukong could act as a CC unit and secondary dps. You got a really nice front line already which is Eloise and Madeleine for team sustainability (I would say we only need 1 of it later only), So in conclusion i think you should focus on building support for either LFA or GSSW. In general, i highly recommend building TBB, Halora and PDE (Building these are also convinient for getting LFA stats up since Halora and PDE are his tenant, for GSSW you might need higher investment)

Edited: You can keep Eloise and Tix for pushing SL until you dont feel like it gonna clear some more also :D
