I feel a main problem in league is the lack of ability to help your team through an early struggle.
If im playing top, and doing well, i hope to win. However, in a heavily team based game like league, this isnt always the case. a game is decided by how the team does as a unit.
but some games are simply decided by the laning phase alone. if my bot lane gives 5 kills to the enemy ADC, theres a high chance you will lose. why though?
why does something as insignificant as 5 kills so game changing? this is because only the jungler can support the failing lane. if I want to help my bot lane, i have to abandon top (which is hard to hold because jungling is an enforced meta pick) which is too risky since i will likely lose my tower.
this isnt a problem in Dota because of the accessibility of the 135 gold TP scroll. any lane can quickly TP into a lane and instantly assist that lane. while someone uses a TP to cover the lane. this allows much more teamwork than "wow can bot stop feeding ff at 20 pls"
just a thought
