Pros
Pro 3 different maps
There are three different maps that users can play on, which offers a bit of a change up of play and familiarity as well as allows for the player to not get burnt out on a singular stage played over and over again.
Also, there are game modes with new experimental maps.
Pro Largest diversity of champions with unique play styles
Having 141 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.
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 Fun mode every weekend! New fun mode every second weekend
There are a number of fun modes that are switched on Friday evening and switched off Monday evening, rotating every two weeks.
This include always highly awaited URF (Ultra Rapid Fire), AR URF (all-random URF), Nexus Siege, Hunt of the Blood Moon, Legend of the Poro King, Doom Bots of Doom, Hexakill, Ascension etc.
Pro Constant champion reworks and visual updates
They are updating champions that have "outdated" gameplay/visuals on a regular basis. And usually, they hit bull's eye, giving those champions new life and making them feel "right" to the player (there are much more praises than complaints from the community).
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.
Con Champions takes time to unlock
While in Dota 2 every hero is for free and you can catch up on which characters you like, you have to buy them in LoL and spend a lot of time and hopefully (what they want you to do). While it's not P2W, it is very time-consuming to unlock other characters.
Con Lower-end PCs sometimes give you an fps that is too low to compete
Success in League of Legends is very much dependent on your reaction-time. If you're playing with a fluctuating and low fps, you will have trouble competing with others. You will not be able to hit your abilities, kite with autoattacks or dodge enemy abilities on time.
Con It sucks
Ask any player that plays this game and he will tell you it sucks, do you need any other reason?
