There are a lot of good players now, period. There are also more viable strategies than just spamming Illums. This list is certainly outdated, not that it was ever perfect, but it wasn't my place to say, because it was How's list and he put in the work maintaining it. It is a pain in the butt to do stuff like this on the side, which is why people who said they were going to make their own lists never maintained them.
I'd suggest for someone else to maintain their own version of a list, but quite frankly it is hard to determine the relative skill level of people when there is a huge amount of smurfing going on. To get an exact idea for someone's skill level, you would have to play against that person in a 1v1, and both against and with that person in a team game. It is pretty hard to get a sense of relative skill levels when you never know who you are playing against, and it is possible to have an inflated sense of self esteem when you smurf people and surprise them while they are contending with who they believe to be the main threat.
Overall, I think there are a lot of veteran players now....but without a 1v1 ladder system to track stats across many games, it is pretty hard to gauge relative skill levels. Anyone can win or lose a particular game to a good player, and team games make it hard to tell relative skill because there are so many feeds and 2v1 situations going on.
