Captain mode got it's final deathblow dealt with 1.5. Faction balance is completely skewed still, instead of 2 superior factions and 1 completely useless one, we now have 3 superior factions, 2 useless ones and one that's barely usable.
With shock buffed the only real comps are either 1 shield 5 shock, or 6 shock. Archers used to be a pretty hard counter to shock units, but now that's gone with the archer AI not being able to use bows due to new combat parameters. Cavalry AI was always bad, but with 1.5 they don't even use their lances anymore. Menavlions are not used by menavs units if they have a sword in hand, which means palatine guards are almost useless, and taking a sword on menav units (even if completely stupid) is now a death sentence to the whole unit.
Throwing weapons are also useless because of the same combat parameters that ruined archers, which leads to how skirmishers were always a useless class in captain, just as well as peasant units (discounting Warriors with improved armor and 2h axe, which is more powerful than Berserkers as a choice, and peasant before the billhook got nerfed). The only factions that could make use of the peasant units AS peasant units were Battania, and Khuzait, (battania being the worst lost useless faction out of the 6) and even those only when you could draw the right team comp out of the opposing team, and pulling them in a spot where they could be easily overwhelmed.
Captain has been in shambles for a long time, but the recent changes have made it near unplayable. The community has nesrly died in the span of the last 4 or so weeks that we have been playing this latest patch.
This comes off as incessant whining and not particularly helpful criticism. They just launched a big patch with a lot of fixes that players had been requesting.
The issue seems to be your understanding of the development cycle and the amount of time it takes to actually produce content or make changes.
They've done a lot of good work and obviously they will continue working on it.
The glory days of Warband were the result of many, many years of effort. We're still in early access as you mentioned. The developers are listening, many of the changes for 1.5 were the result of extensive criticism from the forums.
But if we are really passionate about M&B and are sincere with our concerns, we should strive to provide constructive criticism in a way that is not derogatory, condescending, or useless.
I am the person you are mentioning and we are already working on most of the items provided by the Captain's League community.
