Thanks! I'll try out what you've said and adjust the guide accordingly.

it's not the most detailed guide, but it gets the point across. I've got a couple suggestions in terms of items and skill sequence.

items:
ghostblade; flat ArP, active movespeed/attack speed everything good about AD Rammus in an item.

stark's fervor; pretty much the same, more flat ArP, some attack speed and life steal to boot, this would prolly be a 6th slot item for me unless they're building armor but it's worth it.

Frozen Mallet; I would put this in a core build, above a 2nd PD personally I'd prolly get it as 2nd item (boots of mob, ghostblade, mallet)

skill sequence:
this is more personal preference than fact, but IMO you're better off ranking taunt and curl as priority, with just a point in powerball at the start. rank5 taunt, runes and ghostblade =81 armor pen, that should have you doing true dmg to pretty much everyone.

Defensive Curl: gives you extra ad and enough armor/MR to stand and fight, this is why I'd get frozen mallet so early. by the time you've completed it no one should be able to stand toe to toe with you.

Powerball: IMO you get this rank 1 at the start and leave it there, powerball's main purpose is to get you to the fight/tower once you're there it's not particularly usefull, especially if you've got frozen mallet.

well that's my 2 cents, hope it helps.
