The ring event that came with Chaos

I'm not sure if I remember correctly but weren't the equips nerfed?

Yes, all the explorer rings stopped increasing critical damage, which means my Cruel Ring gives +3 attack and +5% critical chance, while a Critical Ring gives +2 attack and +10% critical chance. It used to be that my Cruel Ring added +3 attack, +5% critical chance, and +20% critical damage, while a Critical Ring added +2 attack, +10% critical chance, and +10% critical damage.

Now that we have a chance at re-obtaining the rings, I just want to know if that 5% critical rate is better than the 1 extra attack on my Cruel Ring, and if so how much better is it?

You need to get a level 40+ character to level 40 times, so you can still get it on other adventurers. As for the items, I don't believe they are nerfed. Don't forget, adventurer rings aren't the only items. You can get earrings (Cygnus), a mask (Dual Blade), Lilin's Ring (Aran), Dragon Glasses (Evan), and the Resistance Ring (Resistance). All items have weapon attack, can be worn by any class, and can be transferred through account (at least one time). There's a thread around the forums somewhere.

Yeah, I know about the other items, and I know about the leveling 40 times for level 41+ people. I said that I'd make a new one because every character on my main account would have to reach at least level 103 to get their items. I also don't need the earrings, resistance ring, Aran ring, or Evan glasses, and the mask for Dual Blades is thief only. This leaves the Explorer's Critical Ring, but I don't want to delete any of my characters and I don't have the money to get a new slot, which is why I'm asking just how big a deal that 5% critical chance would be over 1 extra attack point.
