Incarnam and Astrub are F2PAreas that contain around a month of playtime (depending if you're a completionist it might even be enough for a few). If you want to discover loads of other Areas, you will need to become P2P.
Profession levels have been increased from 100 to 200 (and from 30 to 60 for F2P players).
When crafting Equipment, the level of the Equipment determines the Profession level you will need to craft it (i.e. a Level 163 cloak will need a Level 163 or higher Tailor to craft it).
When leveling Professions with crafts, the closer the craft's level is to the profession's level, the more XP you will get, so it's almost always better to craft the highest possible item (unless there is a very easy recipe that is of lower level and can be mass crafted).
v2.43 - Dofus Levels have been modified to fit the difficulty of the questlines.
v2.44 - Single account Servers have been added, players can only use one account there, which means more grouping up for newer returning players, as opposed to normal Servers where end-game is the main focus.
v2.45 - Spell Variants have been added.
Spell Points are removed, regular Spells now have 3 Levels, they level up automatically as the Character's Level increases up until Level 100. Spell Variants only have 1 Level, they are unlocked over Levels 100~200.
