You miss the point so badly I don't see it worth explaining to you but I am well versed in wasting my time.
Organisations like Nerdrage don't give a fuck about TF2 and "sponsor us" because it costs them next to nothing to do so, half a chance their meetings about whether to engage in TF2 are based on if they ordered 6 too many T-shirts. The tiny amount of exposure Nerdage give this game is laughable so their loss shouldn't be mourned with an article on TFTV or a mention in Backcap or even this forum thread.
I shed a tear when Admirable went to Overwatch because his loss to European TF2 is actually worth a 1 hour video and a long article, but he gets neither. People who give to this community are undervalued far too much and substituted for some organisation that doesn't give a fuck about this game.
I find it laughable you think having an organisation want their team to be successful means anything when the point of an organisation / sponsorship in the real world is to financially subsidize amateurs to help them improve their performance. Football teams get sponsors to invest in improving their training conditions or pay for bigger salaries to attract better players to the club. I mentioned in Div 6 getting better perks from some University Student because my Div 6 team didn't have a server and this guy gave us a server and some other stuff that wasn't as important as a server which enabled us to practise more often and do tactics sessions and so forth to improve our team, so their organisation, though it was a bunch of Scottish students attempting to make a gaming community which died when they got bored and moved on with their lives gave way more than any of these major organisations have ever done.
If an organisation wants to have me shed a tear for it, it should put money where it's mouth is. Maybe if Nerdrage supported their TF2 team by offering them incentives to go to LAN they might put extra time to improve their results? I can't speak for their team, but if a team is offering me free travel to compete at a LAN I might actually put more effort practising than I normally do. Give the team some peripherals that they might actually need? I know if an Org came to me and said "we'll get you a new Monitor and Graphics card cos yours is shit" I would jump at the opportunity. I am not saying this is the reason why they haven't done well or not, I just find it amusing they can sit there and say "dropping you cos of bad results" but don't offer anything (ie the purpose of a sponsor / organisation) to support their players?
Nope, they offer you some cheap shirts and in return you get to promote their brand to TF2 players who may decide to care about their OW of CS:GO team cos they say their name in TF2. Amazing perks!
So yeah they are a joke to me, getting involved in this game because they're not serious about it and I don't blame them for not being serious about it, but we shouldn't be serious about them and give them some special status.
