FireLance said:The problems with this approach are:
1. Not all constant abilities may be integral to the class concept (some people don't want familiars/animal companions/special mounts, for example), so it would not be a good idea to build them directly into the class features.
2. Some constant abilities may be too powerful for a 1st-level character.
1. They could fall under something similar to rogue tactics (artful dodger vs. brutal scoundrel).
2. There could be "class abilities" that are picked up at higher levels. At the very least, I would expect paragon paths and epic destinies to have some more options when it comes to class abilities and tactics that are more constant in nature.
