I disagree. This is fine for starting Kara. Do the math -- for DPS, it's almost identical to Beast Lord set, with less INT/MP5, but a lot more STA. The best hunter shot rotation uses very little mana (auto/steady). Take the STA. BL set has the edge for traps, but again, that's not important for Kara.
Can you get better blues from instances pre-kara? Yes, slightly. Is it worth doing? Nope (except for the epic chest from MgT). In the time it takes to collect those instance blues, you could get at least 3 pieces of S2 gear, which would put you WAY ahead of someone going the instance route. This set is so easy to get that the upgrades from other instance blues just aren't worth it anymore. If you can't go right into Kara with this set, get a bit of S2 and you're still much stronger than a hunter with the best possible BC blues from instances, for much less effort.
