Everything that needs ot be said has been,
back in the day it was the best game of its genre just marketted REALLY badly
Just to give you an idea of how long it takes to get pvp "ready" when i played
-level 1 to 45 powerleveling takes about 3 days (this means optimised groups of higher level characters for the sole purpose of leveling the lower level characters)
- on top of this you have master levels, these are additional abilities gained by doing quests.
Basically there are steps on these quests which can only be done in a group, solo and then bigger steps which take 15 (if tailored for the purpose) to 50 people to do
The minimum time is approximately a week; this with 3 full groups of tailored people doing 6 hr stints, this is because on top of actually doing the steps you need to get master level experience to move to the next level
- On top of this you have weapons and armour called Artifacts which are gained by killing certain mobs in varying scenarios, this on average just needs 1 full group (8 people), once you have these artifacts you need unlock them by farming scrolls (3 are needed for each artifact, the drop rates vary on the parts but in total you need a copy of the scroll 1/3, 2/3 and 3/3) once unlocked you need to level them, in a tailored group this takes a few days to a week
Both the above were introduced in the Trials of Atlantis Expansion
- Once you have finished all this there are additional abilities gained by doing Champion Levels introduced in the Catacombs expansion, these again are quests which are done solo to 1 full group, these can be done in a day if you have a tailored group
-I cant comment on what needs to be done in the latest expansion as i retired before it hit
- Finally you need to get yourself armour crafted so that you have your resitances and skills maxed
Once you have done all the above you are ready to go pvp, but you still cant solo

this is because when pvp'ing you get realm points for killing people/doing objectives, these equate to Realm Ranks which give you points for abilities only gainable in pvp.
Around Realm Rank 5 if you are competant you have a fighting chance
I'm not meaning to scare you away from the game, but the reality is the game is 4 or so years old and it is now not very newbie friendly as there is an awful lot to do
