You are very sure people are being mean to you, including being very upset at one of the other moderators here who was defending you, and threatening to report him across multiple threads. All he was doing was telling others to chill out, and on your behalf, mind you.
Honestly, these folks are legitimately giving you their best advice, taking their own personal time to type out long responses with screenshots, searching up video links, and working to help you. None of us get paid to post here. We are all spending our own personal time to do help. But if you hear anything at at blunt, or if someone asks you if you have even had time to apply the advice we have given, you react very poorly to it, and create new threads to complain about the moderators, the posters here, and act as if giving you blunt advice is the same as insulting you.
Usually when people have you have been asking the same questions on the forums now for three weeks+, they ARE trolling us. Getting some sort of fun out of wasting out time and good advice.
The answer to almost every problem you have posted is as follows "Farm champs as food using the videos Quinn linked, and use those newly 60'd legendary champs to progress."
In answer to some specific issues you've brought up.
- Lyssandra is one of the best champions in the game for Arena, getting her faster, to over 280, is about farming 6-6 Campaign for Speed Boots and 6-7 Campaign for Speed Gear. After that, you'll need to farm Dragon.
- Mixed gear is fine. Stats over sets. The only champs you care about sets on is 6 speed pieces for Lyssandra and potentially Lifesteal for Kael so he can farm 12-3 for food.
- Scyl and Thenasil's power are not very important. Champ power is mostly weighted for Crit Rate and Resistance, and therefore has little impact on whether or not a champ can actually perform in game. It is more important that you build them for the job they are going to do in your teams. Don't worry about power, only worry first about Speed, Accuracy and Survivability, for most champs.
- Food farming is simple enough IF you watch the videos. If you cannot understand what the videos are explaining, please DM me and I will see what I can do for you.
I have suggested you message me several times for help, and you have not done so once. Opening new threads to claim what we suggest is impossible, or be angry at everyone here...well, it isn't really making use of our advice, nor personal offers to help you. When people offer to take their personal time to help you, and to help JUST YOU in private, better to utilize that help instead of saying "Done. Just rude players. I will figure it out eventually. Should be able to block players."
Seems to this girl it is extremely rude to attack people offering help, but I am just the fool offering help, so what do I know?
I hope you figure it all out. Any other anger posts from you will be deleted, and you will be given more timeouts to reflect. Have a good day!
