Start with a clear base name
Choose a short word or two that teammates can recognize quickly. Initials, a memorable alias, or a compact word combination work better than a long sentence. A clear base also gives decorations room without overwhelming the result.
Use one strong visual idea
A bold Unicode style, a pair of brackets, or a single symbol is often enough. Combining several fonts and many marks can create visual noise, especially in small interface areas such as a kill feed or squad list.
Test before confirming
Device fonts and game filters change. Paste your choice into the name field and inspect it before using any name-change item. If characters appear as empty boxes, return to a simpler style.
