Indeed, can't agree more...
I mean: I play a Javazon on my Pentium 3 256MB ram (single player though) but that screen is always filled with lightning bolts...I wouldn't know why people should lag because of some skellise >_<
well my computer lags when summoners have too much stuff going.
I dont mind 6-8 skellys or revives but when you have like 2 dozen various summons on the screen it is annoying for lag and also to see whats actually happening.
when i do baal runs on my nec, i used to just have a couple of skellys or in the actual throne room i just used amp and courpse explosion and you dont need summons. Obviously for baal all you need to do is clay golem and decryptify him.
Its not whining, its you being inconsiderate to other players.
Summoners with enigma can gather up thier summons quite nicely to avoid the issue of other players thinking, "Where am I?"
So far as lag goes, that shouldn't be your concern, the game really doesn't have the highest of requirements, if it lags then it's their issue, and not yours. There is a lovely blue box to squelch them too. ; )
So far as baal goes, you really, as others have pointed out, don't 'need' a full army. If you do feel like summoning some, and you have an enigma, try to gather them so that they are with you, it makes it easier for others to see.
