I also thought it would be frustrating farming anything because it always felt like being too slow or too weak for any event or new content which came up.
But the main reason was my chaotic farming in the beginning.
Everyone in my guild was way better than me.
BUT during the last year i got a lot more into the game and now i know what to do and what not to do.
In the beginning i wanted to reach #1 soooo much and it always felt like - with every new content - i could never get to it.
I invested a bit in getting Revan and i got myself in top50 ( for about one week ?) and now i am in top250.
For me its okay because being top3 in arena means a lot of stress, money or Time.
New content or meta related is for arena players. For me, the game is much more than Arena, so i am also very relaxed to new events, chars etc. Because i know i can get it the next or the third Time.
But yeah i understand this frustrating situation but i also understand people who are frustrated with a game that releases new content way too slow.
