I've found myself tricked by the bars in the ping indicator, since one bar can be playable sometimes.. But other times one bar is just absurd. Displaying it as numbers would help a lot.
Maybe just add a little number display when you hover your mouse over the ping bars?
(I believe this game fails at informing every kind of stats in general, since everything is measured in inaccurate bars, but I don't expect OOO or sega to change the way they display stats on items)
Any better suggestions? Thoughts?
Here's already a little rant about this:
