To be honest a phantom dancer is much better then a ghostblade. and i agree with the fact about black cleaver instead of last whisper only if your opponents arnt over 150 armor. once its past that you should go for a last whisper instead since its more armor pen. this is espcialy true if you're fighting champs like ramnmus.

Also i dont think you should pick up the third Bloodthirster due to 2 things. once if your opponent has armor you wont be able to do great dmg. take Rammus for example one the most anoying tanks for Tryn to play against. if he activites his W and has around 300 armor thats around 450 armor. and that take out around 80% less dmg. however with a Last Whisper it becomes around 260ish making it you deal almost twice the Dmg you would normaly do rammus. and if you deal almost twice the damage you would heal 200% the amount instead of 150% with the third Bloodthirster while almost dealing more dmg

You don't keep boots since the 2 phantom dancer makes up for the speed. I've tested it it, even without the boots you get over 400 movement speed and that's plenty speed to chase people with. boots are only for early game in order to get the mobility. however endgame it would be better if u had 2 phantom dancer instead of the boots

Dont pick up last whisper and remove 1 phantom and get a blood thirster and u must take the mastery 15% longer time buffs is great
But its still great keep the work

where are your boots? you need boots and 2 phantom dancers? thats horrible you can go 1 phantom and 1 ghostblade or just 1 ghost blade and 2 bloodthirsters black cleaver instead of last whispere other than that its good
