The OP wasn't talking about the actual ability bonus, but rather the difference in ability bonus from 1st to 30th level. In that time, you get 8 stat increases, which translates to +4 to relevant rolls.Correct but you're forgetting that the primary ability score for your class should be between 16-20 at level 1. Meaning there is an additional +3 to +5 coming from stats that you aren't accounting for.
It is possible. Some folks find it easier to say what they have said before rather than dredging up a link.I'm having a serious case of deja-vu here...
I'm not sure that's true.Well, I've told 4e newbies before:
If you can't hit stuff at level 1, it's only going to get worse.
Point-blank archery, if it must be done ... use a readied action.
Sure, it's likely the DM will make you trigger off your foe's attack, which means they get to swing first before your readied action goes off, but they can't take an OA on their turn.
You even get your prime shot bonus, as well as a possible flank.
