The same way as a zero resilience player can assemble a team and queue for 2v2 or 3v3, he should be able to solo queue in the same way. If this happens to not be a good way of winning arenas, on a short run, this guy will find himself at a very low MMR while those that are doing the right choice, will only have to handle once in a while those zero resilience players, but tend to rise the MMR and then wont have to deal with that kind of player anymore
This is nothing like the gear restriction that was implemented on RBGs, The gear bracket in this other scenario was good, because the RBGs lack MMR system. If the BGs had the MMR system, naturally the low geared players would find each other on a 'low bracket' and the premades would find each other on the 'high bracket'
Im against resilience/gear restrictions on this situation, because the game already have a MMR system for solo queue
