Played for probably around 10 hours over the weekend and I've been enjoying my time with the game so far. I think the criticisms are fair, the game has more then it's share of issues but under all that is a pretty fun shooter.
The game's art design/animation are top notch, controlling the different javelins not only feel great but also different from each other. The different abilities are interesting and it's fun playing with friends. Basically there's more fun to be here then most 60 games on metacritic.
However, if things like long and frequent load times, crashes and bugs are unacceptable to you I'd at least wait on this game for a little bit. Also, speaking of the meta, it seems like this game and others like it in the genre doesn't really get going till the end game. Most of the loot you pick up pre end game are mostly the same, just better versions of the same weapons with different boost.
Personally for me, the meta and design choices aren't hindering my enjoyment. I came to run around in a cool iron man suit and kick ass with friends and that's what we've been doing. I hope EA really does invest the time/money to make this something special down the line, even though realistically I will have moved on by that point, but there is something fun and special here.
