lol nymphora will rape chipper

everything can be used if your playing well i like polly- fast towers

best mid hero would be witch slayer/succu

since witch slayer can abuse mana burning and totaly get you out of farming, or succu wich has mad disable+codex and you got no chance.

succubus is a failure at last hits and wouldnt be able to farm a codex in a short time

No. witch slayer and succubus are not near the best mid heroes.

Probably near the bottom.

Oh i wouldn't say that,
but they are easiely countered.. against a caster like that, you can just get some magic armor..

and succubus, if he does ulti on polly, but polly sets his wards first, who do you think comes out in best shape?
or simply keep a centour w8ing near, to come stun when succu is about to go

The problem is a forsaken archer or arachna would easily out lane a ws or succubus in my opinion

Yes it wouldn't be a problem to outlane them, but with the huge starting gold, they have it abit easier..
