Faction Change and Achievements progress
Hello, I have few questions about interaction between faction changes and achievements. More specifically, I am on my way to do Loremaster achievement and I am currently kind of stuck on 590/685 quests on Kalimdor, I feel that all that is left are long dungeon quests. I was wondering if switching my faction to Alliance will keep my current progress of quests progress since that will open many new quests for me and make getting Loremaster easier.
Also I've seen in sticky topic that it says that faction change from Alliance to Horde is unavailable (Topic is from 2017) but I'm pretty sure I saw people switching that way too.
TL,DR:
Can I switch my faction from Horde to Alliance to make Loremaster achievement more easier, then switch back.
Also if it is possible, is it in any way infringementing rules and policies of warmane?
Thanks in advance.
