I have been gaming for more years then I need to admit to. This has been far my favorite mouse and I have used everything from the logi G series to most of the razers at some point. I even have a steelseries that I really like. However, this has been my favorite to date. I do not thing it matters much when it comes to this game with respect to "gaming mice". But this mouse will do it all and can be set up to be comfortable with interchangeable everything. Including different weight setups. lol. Check it out. Again, prolly no advantage here but you will like it non the less. Ohh, and yes, it is rather ugly. lol
