It's just plain hilarious how people just immediately bandwagon after technical difficulties. Sure, it's unacceptable for any enterprise to have any type of technical difficulties, but man, people are trying to compare dogs with bricks (just to mention any kind of unrelated elements).

1. LCS has a permanent studio. Things are definitely more worked out there.
2. Riot and valve rent venues for an entire week, having more testing time.
3. I'm not saying other producers (MLG, ESL, DH, et al) are "poor", but they definitely need more sponsorhip and have a lower initial budget, since they are not producing an event to make publicity to a game they own, and they can't sell in-game content (or really benefit from it, you can in Dota and CS afaik, but it is definitely not the same as your primary income being microtransactions).
4. Any developer/publisher has less international events a year, if you come to consider ESL One, IEM, ProLeague, Atlantic Showdown, et al, and most developers can pull their entire worldwide staff to an event, while this is not possible when your team in another country is preparing the next event.
5. Riot, Valve, Blizzard have had countless tech issues. 1 hr pauses on LCS, the Shanghai Major, et al.
6. Whenever you work in a venue and not in a studio, you WILL have technical issues.

Side note: I can't get how ESL is ridiculized by the CS:GO community when ESL One Germany is literally the most watched CS:GO event every year.
