And why?

normal...
unlike casual deny matter and much harder

Casual isn't even a real mode. You don't need any last hit ability or lane control, because you can just grab a few levels then run around ganking. Even if someone is getting every lasthit and playing perfectly in lane, if you gank their teammates a few times you get so much gold you don't even need to farm at all. It's just dumb and promotes people running around as 5 like retards with no repercussions.

For example, in a normal game if enemy team commits 5 heroes to a gank, and ends up killing 2 supports, it's often a tradeoff. If the team's carry is farming and maybe takes a tower in return, it isn't really worth it for the enemy to kill those 2 supports because they only gain like ~500 gold as a team split among many heroes whereas the other team's carry gets around ~1.2k from freefarming for 2 mins and last hitting a tower. In casual mode, if this happens the team that ganks the 2 supports gets like 1k gold and can buy much more items and snowball out of control. It's just a mode that even less balanced than normal mode HoN, and that's saying quite alot.

people are already running around like retards, there is more pub training in hon than random noobs posting here
assist gold split to team is lame as well, if a solo kill is done 4x tards get gold for doing fuck all

the thing I like about cm is that you dont lose gold, this makes for faster/aggressive game play
rather than tower hugging/turtle game play.

as far as items go
cm is basically your hero + better items
normal is your hero + less items
so in essence it takes more "skill" to get a kill in normal

in cm
1. get war beast
2. get puzzle box 3
3. bd
4. profit

not necessarily true
controlling the lane is still valuable
you take away their chance for gold by denying and have the lane in the position you want
making it harder to get ganked because you are closer to the tower

but the whole snowball effect is true
gank a couple times and you have all your core while the other team doesnt
have anything to stop you with

oo look someone finnaly realised what i been saying long ago

CM is called casual for a reason... I don't play CM at all anymore for the reason is it causes me to lax up too much. I go back to regular after enough cm games and I'm sloppy as shit. Also I don't like it because hard carries can push their build through even 3 or 4 deaths in a row... Go in team fight, get a kill or two and die... Death doesn't matter to them, still finishing items that are huge on their hero. Enough of that, and unstoppable anyways. There's nothing like harassing down/ganking a hard carry over and over and really effen up the other teams kill potential.

I like playing with my friends that are worse than me..... and im not the best either soooooo yeah

cm is more fun for me because my friends don't know what buying wards/supporting is..... and im forced to suffer support 3-4 players that are worse than myself....
