I'm the guy who actually went out and recruited/helped most of the newbies for a few months straight at the HUB last season. 90% of the players I found played TB, most left, with the majority of those left over like Jish and Sentral moving on to RT mode.
If TB mode were gone entirely then Jish probably wouldn't be on here as opposed to AOP, If I recall correctly all we did was TB until he left to go make a name for himself.
I lost track of most of the people I helped out, but they're still on a few in the Khans, MOD, TTTLA, maybe some in the Claws Henry knows them better than I ever would though. If you remember some dude giving you a safehouse, and a set of tools when you started the game that was probably me.
Reloaded isn't the premier RT server, TB is huge enough to warrent keeping, but most active players don't use it so letting it stay buggy makes sense, and honestly even if you can abuse it, its the fault of the person getting trapped for getting baited. Since you aren't forced to enter.
I can tell you for sure I wouldn't be here without TB mode, heck I mostly TB. And without me more than 10-20 (The other 100-120 Bluesuits I helped quit anyway) bluesuits would have quit as bluesuits instead of quitting at Combat armor or joining a PVP faction. I do admit even when you help people out they'll probably quit after a while, but have a high chance of coming back since they understand the game better.
