Roamers may not make life easier, but I am going to vote yea!! They can be frustrating, but that is the beauty of it! Their allure lies in their elusiveness. These are valuable pokemon that will show up randomly just when you least expect it. Furthermore you have to come up with creative strategies to keep the pokemon from escaping. It's like the disbelief and rush you get from a random encounter with a shiny pokemon. Because it can take a lot of time to get right, capturing a roamer makes me feel that much more complete and proud once it's mine than a stationary encounter. it also gives you something else to do post-game. I wouldn't want to see roaming overused as a mechanic, but for something special like the legendary beasts I will accept the challenge!
