Solutions to always changing the jungle
I get it. We all get it--you don't want it become stale.
Fine.
So randomize the entire thing. Increase the riches and rewards, increase the strengths, gold, xp and buffs from the camps, but where they pop up, and what spawns after you kill the camp is random. As in, you can't know for sure what the best path is to clear because you don't know what exactly has spawned. Make it so that you will have an edge over the other jungler if your teammate can place better wards and scout camps when they get a chance, and even help clear some mid power jungle monster.
Creating plants and other gimmicks is not a solution. Its just a gimmick. Really make the jungle a jungle, and not just a shopping experience were you stroll along a path to collect gold and buffs.
As a sidenote, wouldn't it be interesting if there were thing such a goldmine and mercenary camp, that when claimed, generated a little bit of gold for the team, or generated 1 minion extra per wave (not 1 per lane per wave, just ONE, randomly picked lane).
Im just thinking out loud. Just tossing out ideas. Ways to make the game more interesting.
