I think the argument against the myriad updates is that there is no 'optimal' loadout for a class and players have to match up a set that suits their play style.
IMO this is not a bad thing, however for new / inexperienced players, the default loadouts put them at a real disadvantage with certain classes (hello needlegun).
One thing that can be a disincentive to new players is the sheer amount of available weapons creating too much variety of gameplay styles. New players will literally have to study how the various weapons affect gameplay for themselves and what to expect from their opponents or otherwise just find themselves staring at the wall in spawn more often than having fun.
Very true, but i think thats why they introduced the Coach thing.
