Any issue I saw has been mentioned so imo it went pretty smooth as far as the function of the tournament.
Prize pool not much of a concern for me. The fact that WG offers a function to let you and your clan face others is good enough for me. CW and player made tournaments take a ton of work to set up times and TR. WG fast tracks it, gives you the function and you have at it.
As far as having to pay for credits that doesn't bother me either. You either save enough and load out to be competitive or you take an honest look at your clan and say "nope not ready for this". Not saying limit who can enter on WG part more so feedback to the participants.
TL/DR great job WG and I hope to see more features allowing you to ready up with your clan and get down to tanking.
