Pro The world's biggest e-sports title
League of Legends is the worlds top e-sport title. It raises e-sports to a completely new level, making it real sport, no compromise.
It's funny that people still think of "biggest e-sports" as of "highest prize pool", playing other games, they are acostomed, that there is nothing except Worlds championship and another couple of big events. On the contrary League of Legends is a constant big event. Although it's not the first in highest prize pool on Worlds, its e-sports competition is not limited by rare championships here and there. That's why it is the biggest:
Since 2010, it has several professional leagues, with four major: LEC (Europe), LCS (N.America), LCK(S..Korea), LPL (China) and more than 10 "not major" in Russia, Turkey, Latin America North, Latin America South, Brazil, Vietnam, South-East Asia, Australia and Oceania, Japan, Taiwan and more.
It has big "physical" infrastructure, studios and "stadiums" (usually one per region, but they have more than one in S.Korea and China) are built to take regular championship events. Each region has large "TV"-teams, a large number of analysts and casters. Major regions have more than one caster teams, one of which is English-speaking. Overal, several days a week they produce kinda "6 hours expensive tv show."
They have two seasons a year (splits). In each, 10 teams are competing. Each team plays 2-3 games each week, So the total number of games is around 10-15 a week.
Teams have a large infrastructure. Each has several coaches (strategic, analyst, etc), sports psychologists, cooks, etc.
In major and some other regions, each organization have 10 or more players, who also play in challenger league (as the second team) and/or are raised to play in the main team somewhen and/or for substitutions in the main team.
So, LoL is a real sport and the biggest of e-sports ever.
Pro Largest diversity of champions with unique play styles
Having 144 champions League of Legends ought to offer the greatest diversity, and it delivers.
Many champions have long combos that need precision in positioning and timings on par with fighting games, while others can be effective without combos at all.
Also, many champions feel really unique (not necessarily complicated) in play style, unseen in other MOBAs.
Cons
Con Takes a long time just to learn the game
If you want to get in the game as a new player, you'll have to play for at least a year, or put in hours and hours of studying just to be able to keep up with what characters do what, and what items to get for which character in any given situation. If you take a few months off from the game and return, you will probably have to relearn the whole game again. Almost every Champion is different, not just in stats, but in mechanics and gameplay altogether, from their original launch. The item shop is changing quite frequently, making you have to relearn it every so many months.
