It has its place. In my bank. Haha just kidding. Sort of. It does pretty much exactly what trans/strat/hv combo does in unbuffed content. Which is exactly what pretty much any power set does with most arti combos: the near same as any other combo. Which means we're all just chasing our tails and since trans strat sa is so accomplished already, why waste the time or money changing everything. Once we start talking min max builds, other artis can come into play but literally every single dps can use those 3 and do plenty well enough so it's just the easy cheap option. As far as grand summoning goes, it's fun. It helps with some healing and tanking so I'd only run it in solos duos or alerts. It works against source shart really since the pet artifact hates having too many pets out.
