Ok, so there are probably a few solutions to this, number one being an item which gives you a buff to continue at the current rate of xp gain or drop your xp gain to something closer to the old rate.
The problem is some of us actually want to play the game, not just race to 60.
I recently got a friend into the game, he brought his girlfriend along at we have been playing alongside another friend with SWTOR experience.
We have no challenge playing the game, by the time we got to Taris we were over levelled, mainly due to gaining over 3 levels running through Hammer Station, so we decided to skip story and only do class quests.
We are still gaining ridiculous xp, stupidly we decided to mix it up with some PVP, 90k XP for the daily, literally gained a whole level in the early 30s.
Sure it down-levels you to the planet, but to ~2-3 levels over so there is still no challenge. We want to play the game and enjoy it, so far its just been a bombardment of levels and a feeling of losing content as we don't want to be doing Tatooine at 65. My friends havent even tried the space battles content due to it probably giving them 3 levels first go.
On top of this, gear just feels completely pointless, there is no sense of accomplishment hitting that mark where you can get those new mods, being able to take on that boss.
Please give those who want to play the game the chance to do it at the right level so there is some challenge and fun. It would also be nice to be able to do the FPs at the old levels, getting bolstered to 65 and having level 61 gear drop when you are in the 30s is just disappointing (yes i know the bosses drop the right level gear).
Tone it back so that class story and main planet story will scrape you through, not scrape you through the next planet.
