You do realise that OP wrote this guide in November, speaking about his experiences in September? You can even see the first few replies already advised farming Boba. Be glad that you did not farm GS that even older and more outdated guides recommended.
Although I understand your intent and you're right, I think you missed the point of this whole discussion. Excluding trolls, most ppl here are giving their input as to why or not this guide is useful. Sometimes it may be harsh, but overall it's constructive. As you pointed out, first replies were spot on about Boba, OP shut them down, basing it on his exp and logic. Fair enough.
What I find lacking and kinda inexcusable is leaving this guide as it is, for over a month now. It's saddening that because of that many ppl will be disappointed and discouraged to play this game. Meta change as you well know and so should guides like this. You can see many other topics here, about ships, mods, unit farming and so on, which are updated periodically - it's a common standard.
You can trace many comments in this thread, where ppl including me, ADVISED (word used) OP to change some parts of this guide, since it's outdated (giving examples). Nothing like that happened. Few posts earlier, RAW posted an update in comments, after we debated on current state of the game.
To be clear, I'm thankfull, as many other here, that this guide was posted. It took a lot of effort and dedication to get it done. Many benefited from it, as did I. However, as in real life, things change with time and it should be a standard (as many showed in guides section) to keep popular threads updated. All the data needed to do so is provided in comments. It's not rocket science to sum it up. With all that being said, I credit him immensely for his input. Still when it comes to a follow up it's an F. Especially considering that he shot down most of useful advices ppl gave here. I don't blame him for sticking to his experience, but having an open mind is as important as knowledge.
@wawrzon: what level are you on and what does your arena team look like at the moment (plus where are you ranking)?
64lvl as of yesterday. Top5 arena squad and top1 fleet arena. Currently on Lando(L), QGJ, Boba, GS, STH. Boba is 5* and undergeared, but had to use JC before and staying in top10 was hard. Phasma was useless with previous build. It can still shine a bit with Lando, Boba, STH as base (qgj or gs as fifth).
Even a 1 Bistan can still serve as providing a target lock to make biggs taunt and then be cannon fudder or do some minor dmg from stealth.
Remember I'm on android so no Bistan for me.
