Welcome casually back!
My fav 2 box set up is my Ranger and Enchanter and then the Ranger runs a healer merc and Chanter runs a tank mer. This has done me well on my characters that are 120. so don't listen to the players who say merc suck! They are very useful if you don't over complicate them. I just let mine do what they want to do and we all get along. No special roles or assist etc.
So maybe go with the chanter for your SK?
FV is great and there are many many helpful players. And a couple great guilds. The number one tip for FV is be prepared to learn Elvish right off the bat cause that is the language spoken and without it you will be severely handicapped.
Learning new languages:
1) You can try to buy 1 point in languages from your trainer but that doesn't always work. Or you have to be level 20 when you ask your trainer. Lots of uncertainty on this one since I see players have difficulty with it frequently on FV.
2) You can make a throwaway alt and make it an elf which will then give you the language on him and he in turn can teach your main the elvish thru group chat spam.
3) Get the one point from another player who is willing to group and spam you for a point or two and then group chat spam your merc for the rest of the level.
4) There is a helpful player or two on FV who will super spam your skill in languages, be on the lookout for them to announce in chat that they are offering it. This will take the longest since there is no specific time or days this is offered and you could wait days or weeks for it to happen
You can only learn or teach in the same zone and in group chat. Tells will not work.
Spam means to basically set up a hot key with a sentences to say in group chat that you can just keep clicking over and over. It will raise your level.
