Getting +1 Caster and Max Caster Level every other level is pretty much the same as what the epic and destiny feats for EBs do. So, the question remains, why add more feats to increase EB efficacy when other casters get better just by leveling up? EB cannot make use of Metemagic feats, so making them available for EB seems like a more streamlined option then adding more feats. If they are worried about too much power for EB, then limit it to certain ones, they can do the math to get to the desired damage output.
