Like they care about the MinMaxing issue, the Rep issue, the imbalance of nodes, network level not corresponding to the Rep, kinda abandoned Shurikens, Krakens.
Yeah, they care about the game a lot, no doubt.
Of course they do. They've spent years developing this, and "abandoned Shurikens" are hardly going to be the cause ... well, anything really.
Some of the points are pretty moot - network level isn't supposed to correspond to Rep for example, and nodes are balanced at similar levels (players choose to over level certain nodes, of course higher level nodes are more powerful). Shurikens also got buffed by request, and I believe Kraken was the latest program to see an adjustment.
I'm also not personally convinced min maxing is an issue. No matter where you draw the lines, players will always find a way to push boundaries. Min max networks also aren't invulnerable - the next wave of meta-networks will most likely have ways to defeat these high-value targets.
As for Rep issues, there are two scenarios that spring to mind - super high rep, and super low level. As mentioned above, boundaries were put in place, and players have found ways to either push or break through them. :p What folks don't always consider is the effect that "fixing" these boundaries has on *every* aspect of the game, as they're so intently focussed on that one specific issue.
The team *do* care about every knock on effect of *every* addition to the game, and aren't going to implement something like - for example - removing the online shield to prevent players from remaining logged in. Just because it may "fix" the high rep issue doesn't make it a great option for everyone else.
