This might sound hypocrite coming from a level freezer like myself. But I think level freezing is a mistake and a wrong thing to do now.

This whole lv freezing happened when we first have cross servers sage where most strong people already at max level (highest sage). So lesser strong people started to freeze for adv refine in lower sage. However overtime you can see all 9 sweet spots in all sage brackets filled with strong players. And trust me, there are more than 9 monsters in each sage bracket no matter what level you freeze.

So in order to get that sweet spot, not only you will have to catch up with strong players who probably also spending a lot of money but to beat them and take their place. You are only starting out, I doubt you can do it unless you pay a huge amount of money into this game.

We are at the end of 5.0, there are many ways to obtain adv rune for free that make level freeze not worth it anymore. Another thing is level play a big part in actual fight. The lower level player when fight against a high level player will take level penalty to their secondary stats thus make them a lot weaker than the higher level even if they are on the same power. This happen to me in matsuri all the time, I can't crit or my crit dmg deal very low to people who are at 104 105 when I'm only 84 even tho both side has around 200k bp.

So yes, level freeze nowaday is bullsh!tery, stop listen to those veteran players who probably play years ahead of you. The best way to play the game now is to stop doing plot instance after you unlock all the orbs. Feel free to do all other activities. But unless you are a heavy spender, then sure. Freeze whenever you want.
