If you want to play top lane STOP expecting ganks
Chances are you will rarely get them, if any at all. Dragon is more important than some silly tank/bruiser stomp fest. After I about level 4 you're on your own. This is coming from a top lane main too. Especially if you're a tank. There's 0 reason for junglers to gank for you. With the way the game is now you're useless outside of your CC anyway. Not to mention the game is basically run by adcs when there isn't an assassin to put them in their place.
This goes double for you Tryndamere %%%s. You can go 0/8 the first 10 minutes and still be the most annoying person ever
just got a free kill, their mid and jungler both got an assist, and I just lost my tower, as well as total control over the top half of the map, since I have no hope of 1v1ing the enemy top laner anymore. Is having your top laner completely neutered and the enemy top laner doing whatever they want really worth a drag and a gank attempt on bot? Maybe, if you can manage to snowball bot lane off that specific gank. Otherwise, it's very not worth.
