I understand where you are coming from and it especially impacts the 26 and 27s but after playing with my full level 29 raid team the legit way as we will be from now on to get the extra chest. it took us maybe 5 minutes total for killing the templar. Two defender titans one on each teleport point and drop shields with attack buffs. Everyone unloads all they have on him as his shield stays down the whole time along with a 30%~ attack boost and we emerged triumphant in no time
