So I saw some questions like "is *** good for casual? and for normal?" and I'd like to know if that difference exists.
Because I don't really think on the game mode I'll play when I buy a hero, but I want a good hero, either hard to play or just to have fun
Casual mode picks ARE different than Normal mode picks.
1) The biggest difference is you don't lose gold upon death, this means you can feel safer about picking heroes that are item dependent.
2) The gameplay is CM is much faster and ganking is much more important than in normal mode. In normal mode players are scared to play aggressive because dieing has a huge punishment, CM... not so much. Therefor in CM you will see alot more early game "big plays".
3) No jungling. In CM it is much more effective to earn your gold by killing OTHER PLAYERS than it is fighting creeps all day. If you choose to jungle you will come out underleveled and underfarmed compared to if you were to lane and gank. Therefor dont jungle for 30 minutes and expect to come out and WTFPWNAGE everyone... not going to happen. There are some exceptions, Parasite and Ophelia and still good to jungle as long as they come out for ganks and teamfights.
4) The games generally don't last as long, CM games are quicker and more action packed. Dont pick a late game carry, pick someone that is effective all around, early towers in CM is much more important than lvl 20+ power because most games are over before you even hit lvl 20 anyways.
Tdl is a good pick if you're better then the rest and you can reliably win mid with her,rush bottle > phase + rune ward and just start ganking as soon as you have the silence/charge maxed
you win the game by ganking in cm,not farming,so make sure to pick some kind of gankers like hag/ pyro etc
