And another topic that will just end up confusing the crap out of kids because the majority of this community isn't able to give a nice and direct answer to a nice and clear question.
"Don't but do IF, unless THAT" here,
"Let's clarify my knowledge on something that doesn't even fit your situation" there,
and my personal favorite despite or because of being the worst
"Let's be butt-hurt because i am to stubborn to admit that i misread or didn't contribute something and everytime someone points it out i need to make up another pointless, off-topic excuse or just insult them"...
I have joked about this before and i know this isn't the proper procedure, but i would GLADLY apply as a moderator with this post and keep an eye on stuff like this, by now,
because
-Half the community is pissed about reoccurring topics and questions despite the fact that this forum is everything but easy-to-browse for the novice just looking at the sheer amount of completely different topics popping up all the time at a rate that can confuse the most experienced reader after some weeks of not following, even tho they all contribute to threads being unclear by saltfighting, immaturity and even plain troll sometimes.
- The stickies and searchfunctions can help, if written by experienced members and nicely organized, and if the person reading them doesn't get overwhelmed by terms and content, seeing as those allways go into the hundreds of pages. BUT are NOT an excuse to ambush everyone who just comes in and asks a question, even if it HAD been asked so many times, before.
Just remember that this can be confusing to anybody and yet the community browsing Nintendo-subforums has a comparably big relative amount of children reading in.
And to just stress this again:
-This is a forum, a place to exchange information about a certain topic (hence topics). If the question is direct, give a direct answer! know something you think people don't? make a topic! Got this topic allready? politely link someone to it and request deletion! don't agree with something or don't know about stuff? don't force yourself in by attention-whoring, changing the topic, insulting or to raise some imaginary e-peen from your post-number...
Agression, troll, repeated "additional 'help' " that literally comes up in EVERY topic somewhat scratching the term firmware (Just the example for this case) and off-topic exchange of opinion can happen and isn't that bad if it is just ignored, but generally has no place there unless asked for BY OP, and then only in the appropiate subforums. If you feel to limited by these things, just go and create a private conversation. I feel like that function is underused, anyways
And last but not least, i feel the need to mention that i noticed the irony in my post, because this is as off-topic as it can get, but i actually mean what i said about moderating this forum, and maybe also those for 3DS every now and then, given that i would be granted to do so and the staff wouldn't mind me actually removing all those blatantly confusing and useless posts, should this not get attention i will also copy this and paste it somewhere appropriate to actually apply in the usual order.
Also i feel that i may have over-reacted to this particular situation, so just look at this as a reflection of my feelings towards the entire WiiU-Homebrew-Subforum as it is right now.
So to answer OP at least and hopefully clear any confusion:
Updating should be safe but if you can live with not playing online right now, it's still a better idea not to,
I don't do it, but if you really need to do it, do it now before a less safe firmwareupdate arrives!
EDIT: Call me a hypocrite, but I just btw totally updated because i need to update Sploot since i am visiting some friends to play it with tomorrow, so here is crossing fingers that 5.5.x doesnt make a difference for things, yet.
