Experience points and leveling in 5e is apparently notoriously bad for pacing especially given different player skill levels.
To combat this, we researched several alternative methods and have chosen a hybrid method that allows for leveling for many different play styles and isn't solely based on combat. In addition to normal experience points from combat, we will have an XP pool award for story-based actions that require rolls or achieve goals: "ADVENTURE POINTS". These will be tra.nslated into EXP at certain milestones: guild advancement, quest completion, and other.
Therefore the Character Advancement Chart in the player's handbook will be modified and released when we're done research testing it. It will also be subject to change.
The beauty of ADVENTURE POINTS is quests that have little in the way of combat will still be worth trying and have a sense of progression. But eliminating combat EXP would then make encounters tedious and annoying rather than a means to further progression and a sense of accomplishment. Additionally different playstyles will be level pace independent. I will release this when we start the campaign thread.
