The translation of priorities for Japanese

Hi team, could you please take a look at this community question and review the current translation?
https://community.atlassian.com/t5/Jira-questions/Aboat-Translation/qaq-p/1224546

I think the translation problem is serious.

The priority Japanese translation is now as follows.

Blocker ⇒ブロッカー
Critical ⇒重要
Major⇒ 重度
Minor⇒軽度
Trivial ⇒ 最低

It 's pretty funny ...

重要　and 重度　have the same meaning,

and the 最低 is sometimes used as a bad word、like nasty.

Actually,

it 's not so easy to understand,

so we 're making different priorities .

But It's default ,

so this is a feature that I really want to improve

and ,maybe below is better I think...

Blocker ⇒ブロッカー　
Critical ⇒クリティカル （or 緊急）
Major ⇒ 重要（or 高）
Minor⇒中度 (or 中)
Trivial ⇒ 軽度（or 低）
