presure ur enemy early on u have sustain from grasp and damage from trundle, after early early game only hit the enemy if ur grasp is ready or go in with ur W. Do not all in or play like a true bruiser. ur not trying to get ahead with kills, u pressure the enemy to take horible backs to eat his plates and get leed in farm and exp.

use ur tankines in team fights, support ur adc and midlaner they need the kills to carry even further, huntdown low enemies, weaken tanks and bruisers with ur ult, u also can go eat towers if ur not ahead or eat towers if ur ahead. its trundle he likes towers, but pls communicated with ur team about that dont go split push 24/7 ok. ur very very fcking usefull in the midle of a teamfight.

u can do things like split push bot and eat 1 to 2 towers while ur team makes baron, u pressure the enemies to defend u because if all of them go to baron u will end the game but if they only send 3 people to baron they will lose team fight and atleast 1 tower. ur a pressure making machine with the capability to meet ur team per teleport or just vanish with ur speed, and make lose/lose decicions for the enemies.

dont run thru the frontline to hunt the backline just because thats the main priority, u will get cc`ed and not succed, wait for an engage. ur stile trundle.

i mean yes lifesteal is nice but not necesary, u still have ur passive and grasp with alot of sustain also u have alot mobility wich means u can go back and reset.
why no ghost? ur not running down the enemy ur more poky to stack grasp and get even tankier u dont need ghost u have alot of items and abilitys with movement speed and slows.

Yes trundle is a troll! no but serios its not, it works for me and hopefully for u too i apreciate it if u guys let me know what u think and expirience in the discussions tab. yeah have fun boys.

ps: u guys can laught at me for my english no problem, not my first language.
