There are a couple of rules that force a different kind of conflict. 1) A world rule, god’s rule, that no player ever maliciously attacks another player. This means low-lifes can troll or insult the MC to their heart’s content and he can’t respond with the force he wants to. However, the wording of the rule leaves interesting loopholes the MC eventually uses. 2) Healers are treated and utilized poorly. Since they do little damage, don’t use much armor, and the common tactics of groups in dungeons means that healers are treated as tools and have a short life expectancy since monsters target them frequently. The MC is determined to show them how to fight properly based on his gaming experience and how to be the best healer.
Of the LitRPG webcomics I’ve read, this focuses very heavily on proper group tactics and the role of a healer. It's a little tedious in places if you already know the information, but it’s an overall good story that sticks to its premise.
