As an I/L mage, I summon Ifrit when I boss, train, and leech. Summons are really useful because they do good amount of damage. But I found a glitch. I was leeching my newbie bandit in ludi. And i realized that on my I/L Screen, Teddies were walking on the same place and I couldn't attack them. But, on my bandit screen I couldn't see those teddies! This graphic glitch bothers me so much and it causes a lag. Sorry for my bad explanation, so I prepared a screen shot! They are both same screen at a same time http://postimg.org/image/wvut4m0cl/
That's one of the many reasons we have the Open Beta and a new source, to fix all problems, it's just not ready yet.
