TvP is meant to be designed such that terran expands faster and has more stuff to attack protoss with (attacking being disadvantageous but with opportunity for high risk high reward type activity). LOTV additions havent changed this design but made subtle additions and changes that made this interaction much harder for terran. There are other disadvantages for terran like map design but the core issue that affects every tvp match is the economy disadvantage for terran. These are the main points economy-wise which are straining this design:
- protoss expands faster and safer
- protoss has easier time getting third base (similar to tvz at this point)
- faster nexus’s mean more chrono which means faster tech and better economy
- protoss easily recovers from failed all-ins, cheeses, and failed attacks due to an economy advantage
- protoss can easily get a third/fourth before attacking due to warp gate and warp prism deferring spending
