Is it worth starting?

I'm thinking about rolling into MoP PvE ( dungeons and casual raiding) so I'm asking you guys: Is it worth it?
Is the PvE scene too small? Is it too buggy?
If so, what's the PvP like?
Thanks in advance <3

Moved from cata a month ago and overall everything seems nice so far. Good population and nice competition in arena. BGs popping immediately, world pvp also good. Now about PvE I don't have some opinion cuz I don't do.

PVE in Frostwolf is meh. You rarely see recruitment for dungeons nor raids in global. No pubs whatsoever. Serious PvE guilds can be counted by fingers in 1 hand and most only recruit those who have high iLvl already which a paradox by itself.
Frostwolf is undesirable for a PvE player like me who has absolutely no interest in PvP.

no wonder theres no guilds left if they open a 'fully' working boss but the doors are closed to him and u get ban if u use lock portal to pass through or imaginary 'ninja' looting bans for 'pug' leaders on global coz some fags crying over items w/o knowledge what is ms or os (but thats thanks to gms that ban 'normal' leaders). Bosses working well in endgame instance u also can count on fingers in 1 hand. Every1 is moving from here (PVE content) semewhere else coz its not fun anymore. just stay with pvp if its okay there or go to some older expansion.

I'm not doing PvE, but I see people LFM on global all the time...

Endgame PVE is at the moment in a terribile state, you can't go past Megaera in Throne of Thunder and there's several harsh bugs regarding Galakras in Siege of Orgrimmar, so it's basically 4-bosses SoO runs all week. LFR is dead, RDF is a gamble since most of the time you get trash groups.
PVP can be extremely frustrating but that's pvp for you. Disci priests are extremely broken.
