Since no one is informing the public I'll try
We had a small test on Saturday, with Tercio Cartagena clan and a few Adelstana cavalry members who managed to show up, even though numbers were less than expected they were perfect for testing pike brace feature (P button), which we did in various cav vs pike scenarios. My favorite part was watching the massive frontal charge of cavalry fail due to running into pikes.
The conclusion is, despite a few known glitches which will be fixed, the braced pike does a great job at keeping cav in it's place for this era, which means if a cav regiment attacks a pike formation alone, all they can do is circle and shoot, at least until one skilled and brave horseman manages to ride between braced pikes without being impaled and disrupt their formation, allowing others to charge. Still, brace is not OP, cav can survive the hit at certain angles and speeds, and you can't swirl it around because it deactivates on fast rotation, however it needs more work in tweaking and some nerfing.
All in all it was good fun and guys in pike team reported they "love being pikemen"
And I like extra challenge for cav.
It would be great if more regiments apply for future tests, this mod is quite alive, its just that developers decided not to have events during fifa world cup but there should be more events from now on.
