This is a fairly basic topic overall, and the way its delivered is painful to look at.

For any specific topic there is many great guides on the forums: Specficly Tobei and ICE*

Just a TLDR to This: BP is very important since it represents the weighted stat total of your whole team, so the higher the bp you have the more stats one will have giving them an advantage against lower bp listed enemies, but this is manly a guide line since close amount of bp the fight is more decided by how the person plays and the strength and weaknesses of their units.

It painful in the sense its a giant block of text, which if your goal is to make it so one wouldn't want to read through it than well job well done, Most Irish authors would be proud. If you want to write for forum post than certain content is generally needed, reason why i currently keep to replies. For one, the moderators can get pretty particular with how and where something is posted, this does at least fit with the topic of strategy share since it covers what you think is important strategy of play. I'm not a good source for writing knowledge, though if you want to improve in guide base or technical writing look through guides posted and see where they go right or wrong in their approach, if its more creative writing than stuff like fan fiction or reading novels are good since it helps build ones background for these things.

So i get the feeling this is in part a troll post or something.

Short reply Freedom of speech is rarely an absolute Freedom, even more so when entering the social contract of sub spaces such as forums. I leave it at that before this ends up an endless loop where mods do actually come in.

It quite true that initiative is not the sole deciding factor in a fight, but it is considered the most important single stat in the game do to just the sheer amount that it can affect in battle, or to put simply 99% of the time you want to have the higher initiative. Even the team above can benefit from having the initiative advantage, for heal team getting off a heal before a jinpachi or madara ignites your lineup can be the difference maker, with masked man mean whether or not going for a same position interrupt is viable in a prompt mystery battle, and kushina can benefit by going into round 2 with a suppressing immunity that can easily be comboed into immobile.

Very true, though barrier ninja are still highly valued for many parts of the game at this point. I would say having the total initiative advantage is not as huge now for some teams, though good initiative is really useful, even more so for interrupter ninja like shark Kisame, which if po1 and faster can stop your opponent from getting any mystery that turn. Its definitely a stat that one should't be ignoring if their trying to do well in pvp that's for sure.

Need some more info but would make sense since both team would be about even in power or the kimm would be stronger with 4 full, kimm becomes a tanky god the more hes hit so a blitz setup would stall out once its built. I expect that there was a control failed once or twice, cause i can see a easy win for the itachi team with itachi shisui madara and wind main with dance, since you could lock down the two units with chaos for pretty much the whole battle that way.
