You are still making yourself look silly by calling normal builds "troll". Look at the champions abilities instead of their design. Poppy scales only off AP - building her AD makes about as much sense as an AP Vayne and she should not be built tank since she's a carry-murderer with her ultimate, created to 100-0 faster than a 50 min Nasus.
Tryndamere's Q and E scale off AP, and with a very good ratio. It might not be a diamond-viable build, but it is a viable thing at lower elo and currently the only effective way to play Tryndalol.
Warwick's Q also scales off AP, and at 1.0 ratio.If you want some damage you are better off building AP on him than AD - he's still primarily a tank though. Building AP early in lane also gives him even more sustain.
