In my honest opinion, Ncsoft adjusted the limit from 3 to 7 so people (legit players with macro - not bot farmers) will created more toons and spend more (adena/ncoins) which means more income for Ncsoft, its unfair to these players if they return the limit to 3 since they already invested their time and resources to the additional 4 toons. There are fewer people looking for parties (Kama, CC, Baylor, AF, etc) now because of the XP event, doing field hunting yields more XP than doing instances. Bringing back the limit to 3 can't really address the bot farmers since they have more than 1 PC, have bot programs, have virtual machines, etc. What Ncsoft can do is find a good way to apprehend and ban these bots accounts, and not bring back the old limit of 3. Definitely the upgrade in limit has increased the number of legit accounts being logged but its not the main reason of lag and queue, but increase of bots. Though Ncsoft wasn't able to anticipate the increase of logged accounts (legit/bots) with their current hardware and server infra which they need to address aside from handling bots.
More power to Ncsoft and to all players.
Thank you.
