to 1 - denying opens a whole different lane mechanic as u can deny alot of exp to ur opponent if u r good at denying creeps, it also changes the lane mechanic entirely as u can make ur lane push by denying to gain certain advantages for example runes, basically there are 2 lane mechanics in LoL lasthitting, poking / agression while dota has 3 with the possiblity of denying creeps

to 2 - every good team plays with a jungler to maximize the experience gain, so that there are rarely jungle is just wrong and shows me that u dont know anything u r talkign about. Besides that there are ANCIENT creepcamps, BIG creepcamps, ROSHAN, RUNES aswell ass LANE ENTRY's to either keep track of or to block so YES LIMITED WARDS HURT ALOT AND REQUIRE HELL OF ALOT MORE MAP AWARENESS AND COMMUNICATION
to 3 - yes u can buy back for a certain amount of gold that DOES NOT provide u being instantly back in the fight ( tbh i dont know if u can buyback in LoL or not, i never touched that filthy game )
to 4 - losing gold for dying punishes bad map awareness therefor its kind of a mechanic to be aware of what is going on on the map while u farm right?
i dont need to comment the last sentence as its huge bs

Never played lol, but it has to be bad because i play another game which is less popular, less played, less important in the esport scene.
Legit arguments/makes 100% sense.
