The alternative to Repair Gems is 1500 Repair. You can either ask someone for a repair (which many do it for free), or save up /redeem points until you can get it to 1500, or grind for it, or even a combination of all of these.
No worries. Personally, I try to gather a few opinions from people if I have a suggestion for a feature and what not. I ask a few people (that have played for a while and have a positive reputation) and get their take on the idea to really see if it is worth suggesting or not. Some ideas just need more time to formulate and collect data and opinions for, while others may feel given to suggest.
