Not every event in the game is intended for every player at every level. There are some events that are tiered to try to allow as many players to participate - and succeed - as possible. Players have to keep in mind that while you may have been playing the game for 6 months, some players have played since launch (3+ year now). Designing events that are fun, challenging and feel like and accomplishment for both types of players simultaneously is practically impossible.
New players have plenty of things to farm, events to participate in and things to do. Some new players need to get over their FOMO and just enjoy the game at "their level" - and not expect to be able to play in the same way that those who have 2+ more years invested in the game than they do.
In virtually every aspect of the game, you face opponents in arena, fleet arena, TW (presuming you are in an appropriate guild for your GP/level), etc. that are basically similar to you. Either they started at the same time or have about the same GP, etc. So new players aren't suddenly going to be facing Super-Meta teams in arena because they can't get C3P0 on the first go around. The only exception would be if they have a whale or two who shelled out money to get him...in which case, that's the advantage those whales paid for.
