Proposal #1:

When an enemy dies and it was not you who killed it, say at console: “You
downloaded 5 exp. points from combat data at vinctinicy.”
The text is all wrong, but the idea is giving 10% of base experience when a
friend scores a kill.
The conceptual idea is that when the bot is destroyed, it dumps battle logs to
the Dark Robot Circle. Tux then downloads these files and learns from them. When
it was a human-human death, a nearby bot (?) could have generated the logs and
sent them for the DRC continuous improvement.
It is not said if Tux receives this data from the hacked bot, or from the
destroyed bot, the idea is merely to justify a gameplay issue fix.
You know, when you use a M1cr0s0f7 program, they demand you to agree to send
them reports of program usage for “enhacement”.
All bots, of course, send reports of their usage to MegaSys Reasearch
Facilities, who would use this data to prepare development (eg. if a bot is
killing more with the right hand than the left one, next version would come with
a right hand stronger than left one). Dark Robot Circle took control over this,
though.

Proposal #2:
Reverse Engineering program could allow tux to gain experience points when used
against a bot.
That could also help with the Hacker Playstyle problem: We paralyze you and give
you experience for the bot. Increasing skill level INCREASES paralizy time and
experience gain. For hackers that wouldn't be a problem because they have bots
to protect them, but for non-hackers this means sure death. (It would also
cancel any shielding or invisibility currently active in order to run.)
