Now that I’ve time to comment I’ll try to add some personal experience. Subscription account and Froob are both fun to play. You burned out on Hecklers last time you played (as did I) but now we have dailies for experience of different experience categories. You can play both types of free/pay accounts by rolling up characters on separate accounts, preferably professions that compliment one another on those different accounts.
Buff begging. You’ll be doing it often whether or not you pay or play for free. If you don’t buff beg you’ll suffer through RK or AI daily mission beat downs. Don’t let people tell you that you can level a Martial Artist on the cheap or you won’t need outside buffs. No one plays that way. Few people ever played that way - I started playing August 2001 and we always traded buffs.
For froobs I think pet classes are easiest to level (with buffs of course), engineer leads the pack to about L125-130ish, then bureaucrat becomes the hands down RK mission experience farmer; two charmed enforcer pets and your robotic assistant plus crat only experience pistol, calm nano to quickly split mission and dungeon mobs, experience buff and speech nano’s. MP is very strong endgame by using inner sanctum loot and other special items.
Gauntlet buff is free but sided - which is one reason to roll alts as neutrals since neuts can get the buff from both faction NPC’s. Neutrals can also see both clan and Omni chat which is an advantage, too. Later one can chose to go Omni or Clan.
If you multibox max hard RK missions you can use MP to buff your engineer and crat and then alternate leveling a squad of characters like doctor/trader/agent with your engineer in TEAM missions. Let your melee and ranged characters sponge experience while the bot/pets slaughters the mission.
Yes, there is a trick to rolling your missions from one zone to a preferred mission zone with a whompa entrance near your mission entrance. I’ve always played Clan so I can’t help you with advice. You best bet is to travel by whompa and roll Team missions to see where the mission generator sends you; roll from Avalon and see what happens.
Some excellent dungeon leveling spots being Inner Sanctum first floor @ level 128+. With experience buffs and jobe experience clusters and gauntlet buff you’ll be getting 160k to 250k experience per kill up to level 140 or so - so remember to loot lots of the ToTW jackets to turn into temporary Inner Sanctum passes.
