Frankly my regiment and I are disappointed with how poorly conquest works in this application. The maps all tend to be incredibly laggy, there is little moderation of ramboing soldiers throughout, and the general hectic and disorganized atmosphere was a huge turn off to the linebattle. I just don't think conquest events work well in general.
My thoughts on your points:
The lag is attributed to your own computer. I myself have no more lag than I would at any other event. In regards to rambo'ing, there is little that can be done. There are so many people that get cut off and lost that there are bound to be people where they shouldn't. We can have 10 admins policing everything but really most of those rambos die before we can even find their name on the list. And at the end of the day, having a crap ton of admins isn't fun for those doing the job, or those playing.
I feel like the chaos of conquest is one of the main things I love. Its one style of battle where we can all go crazy and fight relentlessly over an objective. Through huge volleys and charges, we can all get into immediate combat and rip the enemy a new one without having to wait 5 minutes for the rounds to end in battle, or having to march to a fort over and over in siege.
That is just my opinion, and those are mostly because I've been playing the same old same old linebattles for a year now. I know a lot of people don't enjoy the game mode and that is perfectly fine
edit: I hope I didnt come off as rude
just expressing my opinion on the matter
