No. This what You personally don't like - other people do like.
The bots are choosing the paths according to their current emotions and map type. More scarried bots are trying to avoid more danger WPs (to prevent be damaged, killed), neutral emtions - they are trying to find the best solution between geometrical length of the path and its safety/danger, the most aggresive bots are trying to find the shoterest path (regardless of its danger). The feer/aggressivity level depands on few things - like the bot just klled someone (aggressivity increases), got damaged or low health (the feer increases/ aggressivity decrases). On cs_xxx maps CTs are offensive bots, Ts are deffensive. On de_xxx it's opposite situation. Deffensive bots tend to camp more often than offensive ones. I think it works good like it is.

If You want they vistit some spots more often - just place team specific waypoints there.
