My Force Master reached the level cap of 45 and finished off the story so far. The ending of the story was quite interesting, and went off in a new direction. The set up for the next arc is fairly intriguing.
There appears to be a fair number of things to do at 45. Apparently I need to increase my faction PvP level a bit in order to unlock some of the more lucrative dailies. This system of Blade and Soul is pretty neat, as you have to equip your faction uniform to accept and do these quests. The quests are PvE'ish, but you can be attacked by the opposing faction (while wearing your uniform).
BnS also has an interesting system revolving around Prestige Coins. As you kill enemy faction people (players or NPCs) you accumulate Prestige Coins. If you are killed by an enemy player, you drop all your Prestige Coins and the enemy acquires them. You turn your Prestige Coins into a vendor in exchange for faction influence. However, the exchange rate is determined by the number of Prestige Coins you have. If you have less than 10, you get 1 influence per Coin, 11-20 is 2 influence per Coin, and 21+ is 3 influence per Coin. However, the rate applies to all the Coins you are carrying. Thus if you have 20 coins, you turn them in for 40 influence, but if you have 21 coins, you would get 63 influence instead.
The system is designed to push you to carry larger amounts of Prestige on you at all times. The amount of Prestige you are carrying is visible, making you a more lucrative target for enemy players. I thought it was pretty clever.
Of course, this PvP system is fairly optional. There are tons of other pure PvE dailies, and 4-5 dungeons you can run. There's also Mushin's Tower, which appears to be a single-person dungeon consisting of 7 bosses of increasing difficulty. And there's the whole Arena system if you're into formal PvP.
So I'm a bit unsure of what I will do next. I think I will take a tour of the various options and then decide if I want to go with an alt, or move on to a different game.
