Ah, community warfare... the Holy Grail of the MWO franchise. It has always been "really close." I think the worst delay was all the pre-launch hype of "really soon now", and then within six months we find out that they have yet to do any actual design / architecture for the CW component. Yes, I get that they had not "secured" the license, but they "secured" all of the founders money to build it.
At this point, even if they deliver CW, it will not be what we were sold on in the beginning. If PGI had indicated that they hated Battletech lore as much as they seem to now, the founders program would have gone a completely different way. For example, the thing that made Clans so much more powerful was that the technology was painstakingly maintained, while the IS tech was decaying due to politics and infighting. PGI has done a horrible job of representing this in game, significantly boosting the effectiveness of IS weapons.
Think of the difference in a real world example. In early 2000,
some company stole a formula for a type of capacitor used in PC components. But they copied it wrong, and several major brands, including IBM, had massive failure rates due to it. This is why in the TT world, you would have "easy" shots completely miss. Either via misfire, or inaccuracies created by a materials shortage. In this case, the clans have no such issues, or the issues are highly mitigated on the initial invasion.
So PGI should have sat down in closed beta, and thought "wow, what are we going to do?" This is where I think PGI has really failed the BT community the hardest. They are constantly working hard to fix the system, but they have yet to identify where that system is leading to. The earliest indications where that we were going to deliver an experience similar to the titles that have come before, but every choice that they have made since then indicates otherwise.
What would have been nice is if PGI listened to the seasoned players, and worked on a "real" convergence model. This may have made the ability to balance clans vs. IS a much more interesting situation without the need to add a RNG for hit detection. They could have also eliminated ELO and tonnage, and started working out a Battle Value system that may not be the "best", but would have been better that 3/3/3/3.
Sadly, so far all we have seen is "reactionary" coding, with very little direction. Even when we get to see the direction, and provide copious amounts of feedback (see UI2.0 public tests vs. release), things are still done "cowboy style." Like removing repair/rearm. That alone probably destroyed most of the basis for CW, and created a very "boat" friendly economy.
So yeah, CW will be late. Probably another decade or two waiting for the next BT franchise reboot.
