Theorycrafting with Tahm

Tahm is my go-to support in ranked right now, and I like playing him top too (and occasionally jungle). I thought of a build which would properly utilize his health scaling and also turn him into more of a poke champion, feel free to critique/theorycraft with me.

You would start with a ROA to get rid of your early mana problems, give some HP for your ult scaling, give your attacks some oompf, etc. You could also go for righteous glory, but ROA is probably more effective for the purposes of this build. You would follow the build up with Liandry into Rylai, of course getting some sorc boots too. The build would be finished off with a Void Staff and Luden. In some cases, abyssal or zhonya could also be taken. The point of the build is to constantly poke people with your W, basically.

The build is similar to that of a Rumble, and probably works best in toplane.

Cons of this build would be lack of usual tankiness, slight lack of mobility (no dead man's, no righteous, etc.) Pros would be more poke than a usual Tahm, more pushing power
