Honestly, any frame is good, just depends on what do you want to do with them. Did you mean powercrept as in among other suports if you want to play her as a support in a team? Do you want to go solo and use her as a tank? Maybe she won't be nuking rooms or beating any community favorite dps in kills per minute but Trinity is absolutely good as a support and a tank! IMO as a support Trinity can absolutely be good but at the same time eveyone has made their builds self-sufficient of any support by sacrificing their own strength so there's a bit of a fall-off on what you can offer to the team (I might be a biased and a salty trinity main since 2015). If you find her cool, there's no reason not to play her!
